[Cmake] please provide example of use of STRING(REGEX REPLACE ... )

[Bitter, Ingmar (NIH/CC/DRD)]

Hi,

This (below) was very helpful.  Thanks.

STRING(REGEX REPLACE <pattern> <replacement string> 
                     <target variable> <source string>)

Can this syntax clarification be added to CMake.rtf that comes with the
distribution?

PS: the directory names created by CMake have forward slashes, hence the
following sets the project name (or workspace name in VC++60 terms) the
complete path which I find very helpful

###projectDir/build/CMakeLists.txt  // build in separate dir from sources

# find current dir
FIND_PATH(BUILD_PATH CMakeLists.txt . ) 

# remove ":" from path
STRING(REGEX REPLACE ":" "_" PROJECT_NAME ${BUILD_PATH})

# convert "/" to "_"
STRING(REGEX REPLACE "/" "_" PROJECT_NAME ${PROJECT_NAME})

# remove build subdir from path
STRING(REGEX REPLACE "_build" "" PROJECT_NAME ${PROJECT_NAME})

# store new assembled name as project name
PROJECT(${PROJECT_NAME})

STRING(REGEX REPLACE "[1-9]$" "pod" podpage ${manpage})

or

STRING(REGEX REPLACE <pattern> <replacement string> <target variable>
<source string>)

so I think you'd want..

STRING(REGEX REPLACE "\\" "_" PROJECT_NAME ${BUILD_PATH})

or something.. it's a very quirky language ;-)
