CCMake 2.2.3 Docs

ccmake version 2.2-patch 3
------------------------------------------------------------------------------
Name

ccmake - Curses Interface for CMake.

------------------------------------------------------------------------------
Usage

ccmake <path-to-source>
ccmake <path-to-existing-build>

The "ccmake" executable is the CMake curses interface. Project configuration
settings may be specified interactively through this GUI. Brief instructions
are provided at the bottom of the terminal when the program is running.

CMake is a cross-platform build system generator. Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt. Users build a
project by using CMake to generate a build system for a native tool on their
platform.

------------------------------------------------------------------------------
Command-Line Options

-C <initial-cache>
Pre-load a script to populate the cache.

When cmake is first run in an empty build tree, it creates a
CMakeCache.txt file and populates it with customizable settings for
the project. This option may be used to specify a file from which to
load cache entries before the first pass through the project's cmake
listfiles. The loaded entries take priority over the project's
default values. The given file should be a CMake script containing
SET commands that use the CACHE option, not a cache-format file.

-D <var>:<type>=<value>
Create a cmake cache entry.

When cmake is first run in an empty build tree, it creates a
CMakeCache.txt file and populates it with customizable settings for
the project. This option may be used to specify a setting that takes
priority over the project's default value. The option may be repeated
for as many cache entries as desired.

-G <generator-name>
Specify a makefile generator.

CMake may support multiple native build systems on certain platforms.
A makefile generator is responsible for generating a particular build
system. Possible generator names are specified in the Generators
section.

--copyright [file]
Print the CMake copyright and exit.

If a file is specified, the copyright is written into it.

--help
Print usage information and exit.

Usage describes the basic command line interface and its options.

--help-full [file]
Print full help and exit.

Full help displays most of the documentation provided by the UNIX man
page. It is provided for use on non-UNIX platforms, but is also
convenient if the man page is not installed. If a file is specified,
the help is written into it.

--help-html [file]
Print full help in HTML format.

This option is used by CMake authors to help produce web pages. If a
file is specified, the help is written into it.

--help-man [file]
Print a UNIX man page and exit.

This option is used by the cmake build to generate the UNIX man page.
If a file is specified, the help is written into it.

--version [file]
Show program name/version banner and exit.

If a file is specified, the version is written into it.

------------------------------------------------------------------------------
Listfile Commands

The following commands are available in CMakeLists.txt code:

ADD_CUSTOM_COMMAND
Add a custom build rule to the generated build system.

There are two main signatures for ADD_CUSTOM_COMMAND The first
signature is for adding a custom command to produce an output.

ADD_CUSTOM_COMMAND(OUTPUT result
COMMAND command1 [ARGS] [args1...]
[COMMAND command2 [ARGS] [args2...] ...]
[MAIN_DEPENDENCY depend]
[DEPENDS [depends...]]
[COMMENT comment])

This defines a new command that can be executed during the build
process. Note that MAIN_DEPENDENCY is completely optional and is used
as a suggestion to visual studio about where to hang the custom
command. In makefile terms this creates a new target in the following
form:

OUTPUT: MAIN_DEPENDENCY DEPENDS
COMMAND

If more than one command is specified they will be executed in order.
The optional ARGS argument is for backward compatibility and will be
ignored.

The second signature adds a custom command to a target such as a
library or executable. This is useful for performing an operation
before or after building the target:

ADD_CUSTOM_COMMAND(TARGET target
PRE_BUILD | PRE_LINK | POST_BUILD
COMMAND command1 [ARGS] [args1...]
[COMMAND command2 [ARGS] [args2...] ...]
[COMMENT comment])

This defines a new command that will be associated with building the
specified target. When the command will happen is determined by which
of the following is specified:

PRE_BUILD - run before all other dependencies
PRE_LINK - run after other dependencies
POST_BUILD - run after the target has been built

Note that the PRE_BUILD option is only supported on Visual Studio 7 or
later. For all other generators PRE_BUILD will be treated as
PRE_LINK.

ADD_CUSTOM_TARGET
Add a target with no output so it will always be built.

ADD_CUSTOM_TARGET(Name [ALL] [command1 [args1...]]
[COMMAND command2 [args2...] ...]
[DEPENDS depend depend depend ... ])

Adds a target with the given name that executes the given commands
every time the target is built. If the ALL option is specified it
indicates that this target should be added to the default build target
so that it will be run every time. The command and arguments are
optional. If not specified, it will create an empty target. The
ADD_DEPENDENCIES command can be used in conjunction with this command
to drive custom target generation. The command cannot be called ALL.

ADD_DEFINITIONS
Adds -D define flags to the command line of C and C++ compilers.

ADD_DEFINITIONS(-DFOO -DBAR ...)

Adds flags to command line of C and C++ compilers. This command can
be used to add any flag to a compile line, but the -D flag is accepted
most C/C++ compilers. Other flags may not be as portable.

ADD_DEPENDENCIES
Add a dependency between top-level targets.

ADD_DEPENDENCIES(target-name depend-target1
depend-target2 ...)

Make a top-level target depend on other top-level targets. A
top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or
ADD_CUSTOM_TARGET. Adding dependencies with this command can be used
to make sure one target is built before another target. See the
DEPENDS option of ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding
file-level dependencies in custom rules. See the OBJECT_DEPENDS
option in SET_SOURCE_FILES_PROPERTIES to add file-level dependencies
to object files.

ADD_EXECUTABLE
Add an executable to the project using the specified source files.

ADD_EXECUTABLE(exename [WIN32] [MACOSX_BUNDLE] source1
source2 ... sourceN)

This command adds an executable target to the current directory. The
executable will be built from the list of source files specified.

After specifying the executable name, WIN32 and/or MACOSX_BUNDLE can
be specified. WIN32 indicates that the executable (when compiled on
windows) is a windows app (using WinMain) not a console app (using
main). The variable CMAKE_MFC_FLAG be used if the windows app uses
MFC. This variable can be set to the following values:

0: Use Standard Windows Libraries
1: Use MFC in a Static Library
2: Use MFC in a Shared DLL

MACOSX_BUNDLE indicates that when build on Mac OSX, executable should
be in the bundle form. The MACOSX_BUNDLE also allows several
variables to be specified:

MACOSX_BUNDLE_INFO_STRING
MACOSX_BUNDLE_ICON_FILE
MACOSX_BUNDLE_GUI_IDENTIFIER
MACOSX_BUNDLE_LONG_VERSION_STRING
MACOSX_BUNDLE_BUNDLE_NAME
MACOSX_BUNDLE_SHORT_VERSION_STRING
MACOSX_BUNDLE_BUNDLE_VERSION
MACOSX_BUNDLE_COPYRIGHT

ADD_LIBRARY
Add a library to the project using the specified source files.

ADD_LIBRARY(libname [SHARED | STATIC | MODULE]
source1 source2 ... sourceN)

Adds a library target. SHARED, STATIC or MODULE keywords are used to
set the library type. If the keyword MODULE appears, the library type
is set to MH_BUNDLE on systems which use dyld. On systems without
dyld, MODULE is treated like SHARED. If no keywords appear as the
second argument, the type defaults to the current value of
BUILD_SHARED_LIBS. If this variable is not set, the type defaults to
STATIC.

ADD_SUBDIRECTORY
Add a subdirectory to the build.

ADD_SUBDIRECTORY(source_dir [binary_dir]
[EXCLUDE_FROM_ALL])

Add a subdirectory to the build. The source_dir specifies the
directory in which the source CmakeLists.txt and code files are
located. If it is a relative path it will be evaluated with respect
to the current directory (the typical usage), but it may also be an
absolute path. The binary_dir specifies the directory in which to
place the output files. If it is a relative path it will be evaluated
with respect to the current output directory, but it may also be an
absolute path. If binary_dir is not specified, the value of
source_dir, before expanding any relative path, will be used (the
typical usage). The CMakeLists.txt file in the specified source
directory will be processed immediately by CMake before processing in
the current input file continues beyond this command.

If the EXCLUDE_FROM_ALL argument is provided then this subdirectory
will not be included in build by default. Users will have to
explicitly start a build in the generated output directory. This is
useful for having cmake create a build system for a set of examples in
a project. One would want cmake to generate a single build system for
all the examples, but one may not want the targets to show up in the
main build system.

ADD_TEST
Add a test to the project with the specified arguments.

ADD_TEST(testname Exename arg1 arg2 ...)

If the ENABLE_TESTING command has been run, this command adds a test
target to the current directory. If ENABLE_TESTING has not been run,
this command does nothing. The tests are run by the testing subsystem
by executing Exename with the specified arguments. Exename can be
either an executable built by built by this project or an arbitrary
executable on the system (like tclsh). The test will be run with the
current working directory set to the CMakeList.txt files corresponding
directory in the binary tree.

AUX_SOURCE_DIRECTORY
Find all source files in a directory.

AUX_SOURCE_DIRECTORY(dir VARIABLE)

Collects the names of all the source files in the specified directory
and stores the list in the variable provided. This command is
intended to be used by projects that use explicit template
instantiation. Template instantiation files can be stored in a
"Templates" subdirectory and collected automatically using this
command to avoid manually listing all instantiations.

It is tempting to use this command to avoid writing the list of source
files for a library or executable target. While this seems to work,
there is no way for CMake to generate a build system that knows when a
new source file has been added. Normally the generated build system
knows when it needs to rerun CMake because the CMakeLists.txt file is
modified to add a new source. When the source is just added to the
directory without modifying this file, one would have to manually
rerun CMake to generate a build system incorporating the new file.

BUILD_COMMAND
Get the command line that will build this project.

BUILD_COMMAND(variable MAKECOMMAND)

Sets the given variable to a string containing the command that will
build this project from the root of the build tree using the build
tool given by MAKECOMMAND. MAKECOMMAND should be msdev, nmake, make
or one of the end user build tools. This is useful for configuring
testing systems.

BUILD_NAME
Deprecated. Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.

BUILD_NAME(variable)

Sets the specified variable to a string representing the platform and
compiler settings. These values are now available through the
CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.

CMAKE_MINIMUM_REQUIRED
Set the minimum required version of cmake for a project.

CMAKE_MINIMUM_REQUIRED(VERSION versionNumber)

Let cmake know that the project requires a certain version of a cmake,
or newer. CMake will also try to be backwards compatible to the
version of cmake specified, if a newer version of cmake is running.

CONFIGURE_FILE
Copy a file to another location and modify its contents.

CONFIGURE_FILE(InputFile OutputFile
[COPYONLY] [ESCAPE_QUOTES] [@ONLY])

The Input and Ouput files have to have full paths. This command
replaces any variables in the input file referenced as ${VAR} or @VAR@
with their values as determined by CMake. If a variable is not
defined, it will be replaced with nothing. If COPYONLY is specified,
then no variable expansion will take place. If ESCAPE_QUOTES is
specified then any substituted quotes will be C-style escaped. The
file will be configured with the current values of CMake variables.
If @ONLY is specified, only variables of the form @VAR@ will be
replaces and ${VAR} will be ignored. This is useful for configuring
scripts that use ${VAR}. Any occurrences of #cmakedefine VAR will be
replaced with either #define VAR or /* #undef VAR */ depending on the
setting of VAR in CMake

CREATE_TEST_SOURCELIST
Create a test driver and source list for building test programs.

CREATE_TEST_SOURCELIST(SourceListName DriverName
test1 test2 test3
EXTRA_INCLUDE include.h
FUNCTION function)

A test driver is a program that links together many small tests into a
single executable. This is useful when building static executables
with large libraries to shrink the total required size. The list of
source files needed to build the test driver will be in
SourceListName. DriverName is the name of the test driver program.
The rest of the arguments consist of a list of test source files, can
be semicolon separated. Each test source file should have a function
in it that is the same name as the file with no extension (foo.cxx
should have int foo();) DriverName will be able to call each of the
tests by name on the command line. If EXTRA_INCLUDE is specified,
then the next argument is included into the generated file. If
FUNCTION is specified, then the next argument is taken as a function
name that is passed a pointer to ac and av. This can be used to add
extra command line processing to each test. The cmake variable
CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set to have code that will be
placed directly before calling the test main function.
CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have code that will be
placed directly after the call to the test main function.

ELSE
Starts the ELSE portion of an IF block.

ELSE(expression)

See the IF command.

ENABLE_LANGUAGE
Set a name for the entire project.

ENABLE_LANGUAGE(languageName)

This command enables support for the named language in CMake.

ENABLE_TESTING
Enable testing for current directory and below.

ENABLE_TESTING()

Enables testing for this directory and below. See also the ADD_TEST
command. Note that ctest expects to find a test file in the build
directory root. Therefore, this command should be in the source
directory root.

ENDFOREACH
Ends a list of commands in a FOREACH block.

ENDFOREACH(expression)

See the FOREACH command.

ENDIF
Ends a list of commands in an IF block.

ENDIF(expression)

See the IF command.

ENDWHILE
Ends a list of commands in a WHILE block.

ENDWHILE(expression)

See the WHILE command.

EXEC_PROGRAM
Run and executable program during the processing of the CMakeList.txt
file.

EXEC_PROGRAM(Executable [directory in which to run]
[ARGS <arguments to executable>]
[OUTPUT_VARIABLE <var>]
[RETURN_VALUE <var>])

The executable is run in the optionally specified directory. The
executable can include arguments if it is double quoted, but it is
better to use the optional ARGS argument to specify arguments to the
program. This is because cmake will then be able to escape spaces in
the executable path. An optional argument OUTPUT_VARIABLE specifies a
variable in which to store the output. To capture the return value of
the execution, provide a RETURN_VALUE. If OUTPUT_VARIABLE is
specified, then no output will go to the stdout/stderr of the console
running cmake.

EXPORT_LIBRARY_DEPENDENCIES
Write out the dependency information for all targets of a project.

EXPORT_LIBRARY_DEPENDENCIES(FILE [APPEND])

Create a file that can be included into a CMake listfile with the
INCLUDE command. The file will contain a number of SET commands that
will set all the variables needed for library dependency information.
This should be the last command in the top level CMakeLists.txt file
of the project. If the APPEND option is specified, the SET commands
will be appended to the given file instead of replacing it.

FILE
File manipulation command.

FILE(WRITE filename "message to write"... )
FILE(APPEND filename "message to write"... )
FILE(READ filename variable)
FILE(GLOB variable [globbing expressions]...)
FILE(GLOB_RECURSE variable [globbing expressions]...)
FILE(MAKE_DIRECTORY [directory]...)
FILE(RELATIVE_PATH variable directory file)

WRITE will write a message into a file called 'filename'. It
overwrites the file if it already exists, and creates the file if it
does not exist.

APPEND will write a message into a file same as WRITE, except it will
append it to the end of the file

NOTE: When using FILE WRITE and FILE APPEND, the produced file cannot
be used as an input to CMake (CONFIGURE_FILE, source file ...) because
it will lead to an infinite loop. Use CONFIGURE_FILE if you want to
generate input files to CMake.

READ will read the content of a file and store it into the variable.

GLOB will generate a list of all files that match the globbing
expressions and store it into the variable. Globbing expressions are
similar to regular expressions, but much simpler.

Examples of globbing expressions include:

*.cxx - match all files with extension cxx
*.vt? - match all files with extension vta,...,vtz
f[3-5].txt - match files f3.txt, f4.txt, f5.txt

GLOB_RECURSE will generate similar list as the regular GLOB, except it
will traverse all the subdirectories of the matched directory and
match the files.

Examples of recursive globbing include:

/dir/*.py - match all python files in /dir and subdirectories

MAKE_DIRECTORY will create a directory at the specified location

RELATIVE_PATH will determine relative path from directory to the given
file

FIND_FILE
Find the full path to a file.

FIND_FILE(<VAR> fileName path1 [path2 ...]
[DOC "docstring"])

Find the full path to a file named by fileName. Paths are searched in
the order specified. A cache entry named by <VAR> is created to store
the result. If the file is not found, the result will be
<VAR>-NOTFOUND. If DOC is specified then the next argument is treated
as a documentation string for the cache entry <VAR>. Note that since
executables can have different extensions on different platforms,
FIND_PROGRAM should be used instead of FIND_FILE when looking for
them.

FIND_LIBRARY
Find a library.

FIND_LIBRARY(<VAR> NAMES name1 [name2 ...]
[PATHS path1 path2 ...]
[DOC "docstring"])

Find a library named by one of the names given after the NAMES
argument. Paths specified after the PATHS argument are searched in
the order specified. A cache entry named by <VAR> is created to store
the result. If the library is not found, the result will be
<VAR>-NOTFOUND. If DOC is specified then the next argument is treated
as a documentation string for the cache entry <VAR>.

FIND_LIBRARY(VAR libraryName [path1 path2 ...])

Find a library with the given name by searching in the specified
paths. This is a short-hand signature for the command that is
sufficient in many cases. The environment variable CMAKE_LIBRARY_PATH
is searched as well as the PATH variable.

FIND_PACKAGE
Load settings for an external project.

FIND_PACKAGE(<name> [major.minor] [QUIET] [REQUIRED])

Finds and loads settings from an external project. <name>_FOUND will
be set to indicate whether the package was found. Settings that can
be used when <name>_FOUND is true are package-specific. The package
is found through several steps. Directories listed in
CMAKE_MODULE_PATH are searched for files called "Find<name>.cmake".
If such a file is found, it is read and processed by CMake, and is
responsible for finding the package. If no such file is found, it is
expected that the package is another project built by CMake that has a
"<name>Config.cmake" file. A cache entry called <name>_DIR is created
and is expected to be set to the directory containing this file. If
the file is found, it is read and processed by CMake to load the
settings of the package. If <name>_DIR has not been set during a
configure step, the command will generate an error describing the
problem unless the QUIET argument is specified. If <name>_DIR has
been set to a directory not containing a "<name>Config.cmake" file, an
error is always generated. If REQUIRED is specified and the package
is not found, a FATAL_ERROR is generated and the configure step stops
executing.

FIND_PATH
Find the directory containing a file.

FIND_PATH(<VAR> fileName path1 [path2 ...]
[DOC "docstring"])

Find the directory containing a file named by fileName. Paths are
searched in the order specified. A cache entry named by <VAR> is
created to store the result. If the file is not found, the result
will be <VAR>-NOTFOUND. If DOC is specified then the next argument is
treated as a documentation string for the cache entry <VAR>. The
environment variable CMAKE_INCLUDE_PATH is searched as well as the
PATH variable.

FIND_PROGRAM
Find an executable program.

FIND_PROGRAM(<VAR> NAMES name1 [name2 ...]
[PATHS path1 path2 ...]
[NO_SYSTEM_PATH]
[DOC "docstring"])

Find an executable named by one of the names given after the NAMES
argument. Paths specified after the PATHS argument are searched in
the order specified. If the NO_SYSTEM_PATH argument is not specified,
the search continues with the system search path specified by the PATH
environment variable. A cache entry named by <VAR> is created to
store the result. If the program is not found, the result will be
<VAR>-NOTFOUND. If DOC is specified then the next argument is treated
as a documentation string for the cache entry <VAR>.

FIND_PROGRAM(VAR executableName [path1 path2 ...])

Find a program with the given name by searching in the specified
paths. This is a short-hand signature for the command that is
sufficient in many cases.

FLTK_WRAP_UI
Create FLTK user interfaces Wrappers.

FLTK_WRAP_UI(resultingLibraryName source1
source2 ... sourceN )

Produce .h and .cxx files for all the .fl and .fld files listed. The
resulting .h and .cxx files will be added to a variable named
resultingLibraryName_FLTK_UI_SRCS which should be added to your
library.

FOREACH
Evaluate a group of commands for each value in a list.

FOREACH(loop_var arg1 arg2 ...)
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
ENDFOREACH(loop_var)
FOREACH(loop_var RANGE total)
FOREACH(loop_var RANGE start stop [step])

All commands between FOREACH and the matching ENDFOREACH are recorded
without being invoked. Once the ENDFOREACH is evaluated, the recorded
list of commands is invoked once for each argument listed in the
original FOREACH command. Before each iteration of the loop
"${loop_var}" will be set as a variable with the current value in the
list.

Foreach can also iterate over a generated range of numbers. There are
three types of this iteration:

* When specifying single number, the range will have elements 0 to
"total".

* When specifying two numbers, the range will have elements from the
first number to the second number.

* The third optional number is the increment used to iterate from the
first number to the second number.

GET_CMAKE_PROPERTY
Get a property of the CMake instance.

GET_CMAKE_PROPERTY(VAR property)

Get a property from the CMake instance. The value of the property is
stored in the variable VAR. If the property is not found, CMake will
report an error. Some supported properties include: VARIABLES,
CACHE_VARIABLES, COMMANDS, and MACROS.

GET_DIRECTORY_PROPERTY
Get a property of the directory.

GET_DIRECTORY_PROPERTY(VAR [DIRECTORY dir] property)

Get a property from the Directory. The value of the property is
stored in the variable VAR. If the property is not found, CMake will
report an error. The properties include: VARIABLES, CACHE_VARIABLES,
COMMANDS, MACROS, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, DEFINITIONS,
INCLUDE_REGULAR_EXPRESSION and DEFINITION varname. If the DIRECTORY
argument is provided then the property of the provided directory will
be retrieved instead of the current directory. You can only get
properties of a directory during or after it has been traversed by
cmake.

GET_FILENAME_COMPONENT
Get a specific component of a full filename.

GET_FILENAME_COMPONENT(VarName FileName
PATH|ABSOLUTE|NAME|EXT|NAME_WE
[CACHE])

Set VarName to be the path (PATH), file name (NAME), file extension
(EXT), file name without extension (NAME_WE) of FileName, or the full
absolute (ABSOLUTE) file name without symlinks. Note that the path is
converted to Unix slashes format and has no trailing slashes. The
longest file extension is always considered. If the optional CACHE
argument is specified, the result variable is added to the cache.

GET_FILENAME_COMPONENT(VarName FileName
PROGRAM [PROGRAM_ARGS ArgVar]
[CACHE])

The program in FileName will be found in the system search path or
left as a full path. If PROGRAM_ARGS is present with PROGRAM, then
any command-line arguments present in the FileName string are split
from the program name and stored in ArgVar. This is used to separate
a program name from its arguments in a command line string.

GET_SOURCE_FILE_PROPERTY
Get a property for a source file.

GET_SOURCE_FILE_PROPERTY(VAR file property)

Get a property from a source file. The value of the property is
stored in the variable VAR. If the property is not found, VAR will be
set to "NOTFOUND". Use SET_SOURCE_FILES_PROPERTIES to set property
values. Source file properties usually control how the file is built.

GET_TARGET_PROPERTY
Get a property from a target.

GET_TARGET_PROPERTY(VAR target property)

Get a property from a target. The value of the property is stored in
the variable VAR. If the property is not found, VAR will be set to
"NOTFOUND". Use SET_TARGET_PROPERTIES to set property values.
Properties are usually used to control how a target is built.

The read-only property "LOCATION" specifies the full path to the file
on disk that will be created for the target. This is very useful for
executable targets to get the path to the executable file for use in a
custom command. The read-only property "TYPE" returns which type the
specified target has (EXECUTABLE, STATIC_LIBRARY, SHARED_LIBRARY,
MODULE_LIBRARY, UTILITY, INSTALL_FILES or INSTALL_PROGRAMS). This
command can get properties for any target so far created. The targets
do not need to be in the current CMakeLists.txt file.

GET_TEST_PROPERTY
Get a property of the test.

GET_TEST_PROPERTY(test VAR property)

Get a property from the Test. The value of the property is stored in
the variable VAR. If the property is not found, CMake will report an
error.

IF
Conditionally execute a group of commands.

IF(expression)
# THEN section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
ELSE(expression)
# ELSE section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
ENDIF(expression)

Evaluates the given expression. If the result is true, the commands
in the THEN section are invoked. Otherwise, the commands in the ELSE
section are invoked. The ELSE section is optional. Note that the
same expression must be given to IF, ELSE, and ENDIF. Long
expressions can be used and the order or precedence is that the
EXISTS, COMMAND, and DEFINED operators will be evaluated first. Then
any EQUAL, LESS, GREATER, STRLESS, STRGREATER, STREQUAL, MATCHES will
be evaluated. Then NOT operators and finally AND, OR operators will
be evaluated. Possible expressions are:

IF(variable)

True if the variable's value is not empty, 0, FALSE, OFF, or NOTFOUND.

IF(NOT variable)

True if the variable's value is empty, 0, FALSE, OFF, or NOTFOUND.

IF(variable1 AND variable2)

True if both variables would be considered true individually.

IF(variable1 OR variable2)

True if either variable would be considered true individually.

IF(COMMAND command-name)

True if the given name is a command that can be invoked.

IF(EXISTS file-name)
IF(EXISTS directory-name)

True if the named file or directory exists.

IF(variable MATCHES regex)
IF(string MATCHES regex)

True if the given string or variable's value matches the given regular
expression.

IF(variable LESS number)
IF(string LESS number)
IF(variable GREATER number)
IF(string GREATER number)
IF(variable EQUAL number)
IF(string EQUAL number)

True if the given string or variable's value is a valid number and the
inequality or equality is true.

IF(variable STRLESS string)
IF(string STRLESS string)
IF(variable STRGREATER string)
IF(string STRGREATER string)
IF(variable STREQUAL string)
IF(string STREQUAL string)

True if the given string or variable's value is lexicographically less
(or greater, or equal) than the string on the right.

IF(DEFINED variable)

True if the given variable is defined. It does not matter if the
variable is true or false just if it has been set.

INCLUDE
Read CMake listfile code from the given file.

INCLUDE(file1 [OPTIONAL])
INCLUDE(module [OPTIONAL])

Reads CMake listfile code from the given file. Commands in the file
are processed immediately as if they were written in place of the
INCLUDE command. If OPTIONAL is present, then no error is raised if
the file does not exist.

If a module is specified instead of a file, the file with name
<modulename>.cmake is searched in the CMAKE_MODULE_PATH.

INCLUDE_DIRECTORIES
Add include directories to the build.

INCLUDE_DIRECTORIES([BEFORE] dir1 dir2 ...)

Add the given directories to those searched by the compiler for
include files. If BEFORE is specified, the directories are prepended
onto the current list of directories instead of appended.

INCLUDE_EXTERNAL_MSPROJECT
Include an external Microsoft project file in a workspace.

INCLUDE_EXTERNAL_MSPROJECT(projectname location
dep1 dep2 ...)

Includes an external Microsoft project in the generated workspace
file. Currently does nothing on UNIX.

INCLUDE_REGULAR_EXPRESSION
Set the regular expression used for dependency checking.

INCLUDE_REGULAR_EXPRESSION(regex_match [regex_complain])

Set the regular expressions used in dependency checking. Only files
matching regex_match will be traced as dependencies. Only files
matching regex_complain will generate warnings if they cannot be found
(standard header paths are not searched). The defaults are:

regex_match = "^.*$" (match everything)
regex_complain = "^$" (match empty string only)

INSTALL_FILES
Create install rules for files.

INSTALL_FILES(<dir> extension file file ...)

Create rules to install the listed files with the given extension into
the given directory. Only files existing in the current source tree
or its corresponding location in the binary tree may be listed. If a
file specified already has an extension, that extension will be
removed first. This is useful for providing lists of source files
such as foo.cxx when you want the corresponding foo.h to be installed.
A typical extension is '.h'.

INSTALL_FILES(<dir> regexp)

Any files in the current source directory that match the regular
expression will be installed.

INSTALL_FILES(<dir> FILES file file ...)

Any files listed after the FILES keyword will be installed explicitly
from the names given. Full paths are allowed in this form.

The directory <dir> is relative to the installation prefix, which is
stored in the variable CMAKE_INSTALL_PREFIX.

INSTALL_PROGRAMS
Create install rules for programs.

INSTALL_PROGRAMS(<dir> file1 file2 [file3 ...])
INSTALL_PROGRAMS(<dir> FILES file1 [file2 ...])

Create rules to install the listed programs into the given directory.
Use the FILES argument to guarantee that the file list version of the
command will be used even when there is only one argument.

INSTALL_PROGRAMS(<dir> regexp)

In the second form any program in the current source directory that
matches the regular expression will be installed.

This command is intended to install programs that are not built by
cmake, such as shell scripts. See INSTALL_TARGETS to create
installation rules for targets built by cmake.

The directory <dir> is relative to the installation prefix, which is
stored in the variable CMAKE_INSTALL_PREFIX.

INSTALL_TARGETS
Create install rules for targets.

INSTALL_TARGETS(<dir> [RUNTIME_DIRECTORY dir] target target)

Create rules to install the listed targets into the given directory.
The directory <dir> is relative to the installation prefix, which is
stored in the variable CMAKE_INSTALL_PREFIX. If RUNTIME_DIRECTORY is
specified, then on systems with special runtime files (Windows DLL),
the files will be copied to that directory.

ITK_WRAP_TCL
Run CABLE to generate Tcl wrappers.

ITK_WRAP_TCL(target-name config-file1 [config-file2 ...])

Run CABLE on all the configuration files to generate Tcl wrappers.
The generated sources are added to a target of the given name. This
command is provided for use by the Insight Toolkit (ITK) because it
was originally written before loaded commands were supported.

LINK_DIRECTORIES
Specify directories in which to search for libraries.

LINK_DIRECTORIES(directory1 directory2 ...)

Specify the paths in which the linker should search for libraries.

LINK_LIBRARIES
Link libraries to all targets added later.

LINK_LIBRARIES(library1 <debug | optimized> library2 ...)

This is an old CMake command for linking libraries. Use
TARGET_LINK_LIBRARIES unless you have a good reason for every target
to link to the same set of libraries.

Specify a list of libraries to be linked into any following targets
(typically added with the ADD_EXECUTABLE or ADD_LIBRARY calls). This
command is passed down to all subdirectories. The debug and optimized
strings may be used to indicate that the next library listed is to be
used only for that specific type of build.

LOAD_CACHE
Load in the values from another project's CMake cache.

LOAD_CACHE(pathToCacheFile READ_WITH_PREFIX
prefix entry1...)

Read the cache and store the requested entries in variables with their
name prefixed with the given prefix. This only reads the values, and
does not create entries in the local project's cache.

LOAD_CACHE(pathToCacheFile [EXCLUDE entry1...]
[INCLUDE_INTERNALS entry1...])

Load in the values from another cache and store them in the local
project's cache as internal entries. This is useful for a project
that depends on another project built in a different tree. EXCLUDE
option can be used to provide a list of entries to be excluded.
INCLUDE_INTERNALS can be used to provide a list of internal entries to
be included. Normally, no internal entries are brought in. Use of
this form of the command is strongly discouraged, but it is provided
for backward compatibility.

LOAD_COMMAND
Load a command into a running CMake.

LOAD_COMMAND(COMMAND_NAME <loc1> [loc2 ...])

The given locations are searched for a library whose name is
cmCOMMAND_NAME. If found, it is loaded as a module and the command is
added to the set of available CMake commands. Usually, TRY_COMPILE is
used before this command to compile the module. If the command is
successfully loaded a variable named

CMAKE_LOADED_COMMAND_<COMMAND_NAME>

will be set to the full path of the module that was loaded. Otherwise
the variable will not be set.

MACRO
Start recording a macro for later invocation as a command.

MACRO(<name> [arg1 [arg2 [arg3 ...]]])
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
ENDMACRO(<name>)

Define a macro named <name> that takes arguments named arg1 arg2 arg3
(...). Commands listed after MACRO, but before the matching ENDMACRO,
are not invoked until the macro is invoked. When it is invoked, the
commands recorded in the macro are first modified by replacing formal
parameters (${arg1}) with the arguments passed, and then invoked as
normal commands. In addition to referencing the formal parameters you
can reference the variable ARGC which will be set to the number of
arguments passed into the function as well as ARGV0 ARGV1 ARGV2 ...
which will have the actual values of the arguments passed in. This
facilitates creating macros with optional arguments. Additionally
ARGV holds the list of all arguments given to the macro and ARGN holds
the list of argument pass the last expected argument.

MAKE_DIRECTORY
Create a directory on the file system.

MAKE_DIRECTORY(directory)

Creates the specified directory. Full paths should be given. Any
parent directories that do not exist will also be created. Use with
care.

MARK_AS_ADVANCED
Mark cmake cached variables as advanced.

MARK_AS_ADVANCED([CLEAR|FORCE] VAR VAR2 VAR...)

Mark the named cached variables as advanced. An advanced variable
will not be displayed in any of the cmake GUIs unless the show
advanced option is on. If CLEAR is the first argument advanced
variables are changed back to unadvanced. If FORCE is the first
argument, then the variable is made advanced. If neither FORCE nor
CLEAR is specified, new values will be marked as advanced, but if the
variable already has an advanced/non-advanced state, it will not be
changed.

MESSAGE
Display a message to the user.

MESSAGE([SEND_ERROR | STATUS | FATAL_ERROR]
"message to display" ...)

The arguments are messages to display. If the first argument is
SEND_ERROR then an error is raised. If the first argument is STATUS
then the message is displayed in the progress line for the GUI.

OPTION
Provides an option that the user can optionally select.

OPTION(OPTION_VAR "help string decribing option"
[initial value])

Provide an option for the user to select as ON or OFF. If no initial
value is provided, OFF is used.

OUTPUT_REQUIRED_FILES
Output a list of required source files for a specified source file.

OUTPUT_REQUIRED_FILES(srcfile outputfile)

Outputs a list of all the source files that are required by the
specified srcfile. This list is written into outputfile. This is
similar to writing out the dependencies for srcfile except that it
jumps from .h files into .cxx, .c and .cpp files if possible.

PROJECT
Set a name for the entire project.

PROJECT(projectname [CXX] [C] [Java])

Sets the name of the project. This creates the variables
projectname_BINARY_DIR and projectname_SOURCE_DIR. Optionally you can
specify which languages your project supports. By default all
languages are supported. If you do not have a C++ compiler, but want
to build a c program with cmake, then use this option.

QT_WRAP_CPP
Create QT Wrappers.

QT_WRAP_CPP(resultingLibraryName DestName
SourceLists ...)

Produce moc files for all the .h files listed in the SourceLists. The
moc files will be added to the library using the DestName source list.

QT_WRAP_UI
Create QT user interfaces Wrappers.

QT_WRAP_UI(resultingLibraryName HeadersDestName
SourcesDestName SourceLists ...)

Produce .h and .cxx files for all the .ui files listed in the
SourceLists. The .h files will be added to the library using the
HeadersDestNamesource list. The .cxx files will be added to the
library using the SourcesDestNamesource list.

REMOVE
Remove a value from a list in a variable.

REMOVE(VAR VALUE VALUE ...)

Removes VALUE from the variable VAR. This is typically used to remove
entries from a vector (e.g. semicolon separated list). VALUE is
expanded.

REMOVE_DEFINITIONS
Removes -D define flags to the command line of C and C++ compilers.

REMOVE_DEFINITIONS(-DFOO -DBAR ...)

Removes flags from command line of C and C++ compilers. This command
can be used to remove any flag from a compile line, but the -D flag is
accepted most C/C++ compilers. Other flags may not be as portable.

SEPARATE_ARGUMENTS
Split space separated arguments into a semi-colon separated list.

SEPARATE_ARGUMENTS(VARIABLE)

Convert the value of VARIABLE to a semi-colon separated list. All
spaces are replaced with ';'. This helps with generating command
lines.

SET
Set a CMAKE variable to a given value.

SET(VAR [VALUE] [CACHE TYPE DOCSTRING [FORCE]])

Within CMake sets VAR to the value VALUE. VALUE is expanded before
VAR is set to it. If CACHE is present, then the VAR is put in the
cache. TYPE and DOCSTRING are required. TYPE is used by the CMake
GUI to choose a widget with which the user sets a value. The value
for TYPE may be one of

FILEPATH = File chooser dialog.
PATH = Directory chooser dialog.
STRING = Arbitrary string.
BOOL = Boolean ON/OFF checkbox.
INTERNAL = No GUI entry (used for persistent variables).

If TYPE is INTERNAL, then the VALUE is always written into the cache,
replacing any values existing in the cache. If it is not a cache
variable, then this always writes into the current makefile. The
FORCE option will overwrite the cache value removing any changes by
the user.

SET(VAR VALUE1 ... VALUEN).

In this case VAR is set to a semicolon separated list of values.

VAR can be an environment variable such as:

SET( ENV{PATH} /home/martink )

in which case the environment variable will be set.

SET_DIRECTORY_PROPERTIES
Set a property of the directory.

SET_DIRECTORY_PROPERTIES(PROPERTIES prop1 value1 prop2 value2)

Set a property for the current directory and subdirectories. If the
property is not found, CMake will report an error. The properties
include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES.

ADDITIONAL_MAKE_CLEAN_FILES is a list of files that will be cleaned as
a part of "make clean" stage.

SET_SOURCE_FILES_PROPERTIES
Source files can have properties that affect how they are built.

SET_SOURCE_FILES_PROPERTIES(file1 file2 ...
PROPERTIES prop1 value1
prop2 value2 ...)

Set properties on a file. The syntax for the command is to list all
the files you want to change, and then provide the values you want to
set next. You can make up your own properties as well. The following
are used by CMake. The ABSTRACT flag (boolean) is used by some class
wrapping commands. If WRAP_EXCLUDE (boolean) is true then many
wrapping commands will ignore this file. If GENERATED (boolean) is
true then it is not an error if this source file does not exist when
it is added to a target. Obviously, it must be created (presumably by
a custom command) before the target is built. If the HEADER_FILE_ONLY
(boolean) property is true then dependency information is not created
for that file (this is set automatically, based on the file's name's
extension and is probably only used by Makefiles). OBJECT_DEPENDS
(string) adds dependencies to the object file. COMPILE_FLAGS (string)
is passed to the compiler as additional command line arguments when
the source file is compiled.

SET_TARGET_PROPERTIES
Targets can have properties that affect how they are built.

SET_TARGET_PROPERTIES(target1 target2 ...
PROPERTIES prop1 value1
prop2 value2 ...)

Set properties on a target. The syntax for the command is to list all
the files you want to change, and then provide the values you want to
set next. Properties that cmake knows about are PREFIX and SUFFIX for
UNIX systems and libraries. CMake also knows about LINK_FLAGS, which
can be used to add extra flags to the link step of a target.
DEFINE_SYMBOL is a symbol that is defined when compiling C or C++
sources. If not set here then it is set to target_EXPORTS by default
(with some substitutions if the target is not a valid C identifier).
PRE_INSTALL_SCRIPT specifies a CMake script that is run prior to
installing the target. POST_INSTALL_SCRIPT specifies a CMake script
that is run after target is installed. For shared libraries VERSION
and SOVERSION can be used to specify the build version and api version
respectively. When building or installing appropriate symlinks are
created if the platform supports symlinks and the linker supports
so-names. If only one of both is specified the missing is assumed to
have the same version number. For executables VERSION can be used to
specify the build version. When building or installing appropriate
symlinks are created if the platform supports symlinks. The
OUTPUT_NAME can be used to set an output name that is used in place of
the target name when creating executables. PROJECT_LABEL can be used
to change the name of the target in an IDE like visual studio.
VS_KEYWORD can be set to change the visual studio keyword, for example
QT integration works better if this is set to Qt4VSv1.0. You can use
any prop value pair you want and extract it later with the
GET_TARGET_PROPERTY command.

SET_TESTS_PROPERTIES
Set a property of the tests.

SET_TESTS_PROPERTIES(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)

Set a property for the tests. If the property is not found, CMake
will report an error. The properties include:

WILL_FAIL: If set to true, this will invert the pass/fail flag of the
test.

PASS_REGULAR_EXPRESSION: If set, the test output will be checked
against the specified regular expressions and at least one of the
regular expressions has to match, otherwise the test will fail.

Example: PASS_REGULAR_EXPRESSION "TestPassed;All ok"

FAIL_REGULAR_EXPRESSION: If set, if the output will match to one of
specified regular expressions, the test will fail.

Example: PASS_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"

Both PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION expect a list
of regular expressions.

SITE_NAME
Set the given variable to the name of the computer.

SITE_NAME(variable)

SOURCE_GROUP
Define a grouping for sources in the makefile.

SOURCE_GROUP(name [REGULAR_EXPRESSION regex] [FILES src1 src2 ...])

Defines a group into which sources will be placed in project files.
This is mainly used to setup file tabs in Visual Studio. Any file
whose name is listed or matches the regular expression will be placed
in this group. If a file matches multiple groups, the LAST group that
explicitly lists the file will be favored, if any. If no group
explicitly lists the file, the LAST group whose regular expression
matches the file will be favored. For backwards compatibility, this
command is also supports the format:

SOURCE_GROUP(name regex)

STRING
String operations.

STRING(REGEX MATCH <regular_expression>
<output variable> <input> [<input>...])
STRING(REGEX MATCHALL <regular_expression>
<output variable> <input> [<input>...])
STRING(REGEX REPLACE <regular_expression>
<replace_expression> <output variable>
<input> [<input>...])
STRING(REPLACE <match_expression>
<replace_expression> <output variable>
<input> [<input>...])
STRING(COMPARE EQUAL <string1> <string2> <output variable>)
STRING(COMPARE NOTEQUAL <string1> <string2> <output variable>)
STRING(COMPARE LESS <string1> <string2> <output variable>)
STRING(COMPARE GREATER <string1> <string2> <output variable>)
STRING(ASCII <number> [<number> ...] <output variable>)
STRING(CONFIGURE <string1> <output variable>
[@ONLY] [ESCAPE_QUOTES])
STRING(TOUPPER <string1> <output variable>)
STRING(TOLOWER <string1> <output variable>)
STRING(LENGTH <string> <output variable>)
STRING(SUBSTRING <string> <begin> <length> <output variable>)

REGEX MATCH will match the regular expression once and store the match
in the output variable.

REGEX MATCHALL will match the regular expression as many times as
possible and store the matches in the output variable as a list.

REGEX REPLACE will match the regular expression as many times as
possible and substitute the replacement expression for the match in
the output. The replace expression may refer to paren-delimited
subexpressions of the match using \1, \2, ..., \9. Note that two
backslashes (\\1) are required in CMake code to get a backslash
through argument parsing.

REPLACE will match the given expression and substitute the replacement
expression for the match in the output. The replace expression may
refer to paren-delimited subexpressions of the match using \1, \2,
..., \9. Note that two backslashes (\\1) are required in CMake code
to get a backslash through argument parsing.

COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and store
true or false in the output variable.

ASCII will convert all numbers into corresponding ASCII characters.

CONFIGURE will transform a string like CONFIGURE_FILE transforms a
file.

TOUPPER/TOLOWER will convert string to upper/lower characters.

LENGTH will return a given string's length.

SUBSTRING will return a substring of a given string.

SUBDIR_DEPENDS
Legacy command. Does nothing.

SUBDIR_DEPENDS(subdir dep1 dep2 ...)

Does not do anything. This command used to help projects order
parallel builds correctly. This functionality is now automatic.

SUBDIRS
Add a list of subdirectories to the build.

SUBDIRS(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...] [PREORDER] )

Add a list of subdirectories to the build. The ADD_SUBDIRECTORY
command should be used instead of SUBDIRS although SUBDIRS will still
work. This will cause any CMakeLists.txt files in the sub directories
to be processed by CMake. Any directories after the PREORDER flag are
traversed first by makefile builds, the PREORDER flag has no effect on
IDE projects. Any directories after the EXCLUDE_FROM_ALL marker will
not be included in the top level makefile or project file. This is
useful for having CMake create makefiles or projects for a set of
examples in a project. You would want CMake to generate makefiles or
project files for all the examples at the same time, but you would not
want them to show up in the top level project or be built each time
make is run from the top.

TARGET_LINK_LIBRARIES
Link a target to given libraries.

TARGET_LINK_LIBRARIES(target library1
<debug | optimized> library2
...)

Specify a list of libraries to be linked into the specified target.
The debug and optimized strings may be used to indicate that the next
library listed is to be used only for that specific type of build

TRY_COMPILE
Try compiling some code.

TRY_COMPILE(RESULT_VAR bindir srcdir
projectName <targetname> <CMAKE_FLAGS <Flags>>
<OUTPUT_VARIABLE var>)

Try compiling a program. Return the success or failure in RESULT_VAR.
If <target name> is specified then build just that target otherwise
the all or ALL_BUILD target is built.

TRY_COMPILE(RESULT_VAR bindir srcfile
<CMAKE_FLAGS <Flags>>
<COMPILE_DEFINITIONS <flags> ...>
<OUTPUT_VARIABLE var>)

Try compiling a srcfile. Return the success or failure in RESULT_VAR.
CMAKE_FLAGS can be used to pass -DVAR:TYPE=VALUE flags to cmake. Some
extra flags that can be included are, INCLUDE_DIRECTORIES,
LINK_DIRECTORIES, and LINK_LIBRARIES. COMPILE_DEFINITIONS are
-Ddefinition that will be passed to the compile line. If srcfile is
specified the files in bindir/CMakeTmp are cleaned automatically. If
OUTPUT_VARIABLE is specified, then the output from the build process
is stored in the given variable. TRY_COMPILE creates a CMakeList.txt
file on the fly, and in that file it looks like this:

ADD_DEFINITIONS( <expanded COMPILE_DEFINITIONS from calling cmake>)
INCLUDE_DIRECTORIES(${INCLUDE_DIRECTORIES})
LINK_DIRECTORIES(${LINK_DIRECTORIES})
ADD_EXECUTABLE(cmTryCompileExec sources)
TARGET_LINK_LIBRARIES(cmTryCompileExec ${LINK_LIBRARIES})

TRY_RUN
Try compiling and then running some code.

TRY_RUN(RUN_RESULT_VAR COMPILE_RESULT_VAR
bindir srcfile <CMAKE_FLAGS <Flags>>
<COMPILE_DEFINITIONS <flags>>
<ARGS <arg1> <arg2>...>)

Try compiling a srcfile. Return the success or failure in
COMPILE_RESULT_VAR. Then if the compile succeeded, run the executable
and return the result in RUN_RESULT_VAR. If the executable was built,
but failed for to run for some reason, then RUN_RESULT_VAR will be set
to FAILED_TO_RUN, and the output will be in the COMPILE_RESULT_VAR.

USE_MANGLED_MESA
Copy mesa headers for use in combination with system GL.

USE_MANGLED_MESA(PATH_TO_MESA OUTPUT_DIRECTORY)

The path to mesa includes, should contain gl_mangle.h. The mesa
headers are copied to the specified output directory. This allows
mangled mesa headers to override other GL headers by being added to
the include directory path earlier.

UTILITY_SOURCE
Specify the source tree of a third-party utility.

UTILITY_SOURCE(cache_entry executable_name
path_to_source [file1 file2 ...])

When a third-party utility's source is included in the distribution,
this command specifies its location and name. The cache entry will
not be set unless the path_to_source and all listed files exist. It
is assumed that the source tree of the utility will have been built
before it is needed.

VARIABLE_REQUIRES
Assert satisfaction of an option's required variables.

VARIABLE_REQUIRES(TEST_VARIABLE RESULT_VARIABLE
REQUIRED_VARIABLE1
REQUIRED_VARIABLE2 ...)

The first argument (TEST_VARIABLE) is the name of the variable to be
tested, if that variable is false nothing else is done. If
TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a
variable that is set to true if all the required variables are set.
The rest of the arguments are variables that must be true or not set
to NOTFOUND to avoid an error. If any are not true, an error is
reported.

VTK_MAKE_INSTANTIATOR
Deprecated. For use only in VTK 4.0.

VTK_MAKE_INSTANTIATOR(className outSourceList
src-list1 [src-list2 ..]
EXPORT_MACRO exportMacro
[HEADER_LOCATION dir]
[GROUP_SIZE groupSize]
[INCLUDES [file1 file2 ..]])

Generates a new class with the given name and adds its files to the
given outSourceList. It registers the classes from the other given
source lists with vtkInstantiator when it is loaded. The output
source list should be added to the library with the classes it
registers. The EXPORT_MACRO argument must be given and followed by
the export macro to use when generating the class (ex.
VTK_COMMON_EXPORT). The HEADER_LOCATION option must be followed by a
path. It specifies the directory in which to place the generated
class's header file. The generated class implementation files always
go in the build directory corresponding to the CMakeLists.txt file
containing the command. This is the default location for the header.
The INCLUDES option can be followed by a list of zero or more files.
These files will be #included by the generated instantiator header,
and can be used to gain access to the specified exportMacro in the C++
code.

VTK_WRAP_JAVA
Deprecated. For use only in VTK 4.0.

VTK_WRAP_JAVA(resultingLibraryName SourceListName
class1 class2 ...)

Create Java wrappers for VTK classes.

VTK_WRAP_PYTHON
Deprecated. For use only in VTK 4.0.

VTK_WRAP_PYTHON(resultingLibraryName SourceListName
class1 class2 ...)

Create Python wrappers for VTK classes.

VTK_WRAP_TCL
Deprecated. For use only in VTK 4.0.

VTK_WRAP_TCL(resultingLibraryName [SOURCES]
SourceListName class1 class2 ...
[COMMANDS CommandName1 CommandName2 ...])

Create Tcl wrappers for VTK classes.

WHILE
Evaluate a group of commands while a condition is true

WHILE(condition)
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
ENDWHILE(condition)

All commands between WHILE and the matching ENDWHILE are recorded
without being invoked. Once the ENDWHILE is evaluated, the recorded
list of commands is invoked as long as the condition is true. The
condition is evaulated using the same logic as the IF command.

WRITE_FILE
Write a message to a file.

WRITE_FILE(filename "message to write"... [APPEND])

The first argument is the file name, the rest of the arguments are
messages to write. If the argument APPEND is specified, then the
message will be appended.

NOTE 1: FILE WRITE and FILE APPEND do exactly the same as this one but
add some more functionality.

NOTE 2: When using WRITE_FILE the produced file cannot be used as an
input to CMake (CONFIGURE_FILE, source file ...) because it will lead
to an infinite loop. Use CONFIGURE_FILE if you want to generate input
files to CMake.
