[CMake] Copy target from different configurations

[Daniel Tavares]

I'm using CMake 2.6.4, Visual Studio 8 2005 generator.

I'm going to use $(TargetPath) for now. The command is wrapped in a
macro, so it's easy to replace it with a generator-independent way.
Right now I just need to get this working in Visual Studio so I can roll
CMake out to the rest of the team.

Thanks for helping.

Unfortunately at least in version 2.6.4 the local visual studio 7
generator doesn't honor the cmake output path settings so some of the
suggestions for that version at least will not work.

If you're using the newer visual studio generator (you don't specify)
you can take advantage of the VS macros expansions in your custom
command:

if (MSVC)
    add_custom_command (TARGET ${PROJECT_NAME}  POST_BUILD COMMAND
copy "$(TargetPath)" "${YOUR_DEST_PATH}")
endif ()

Notice that the $(TargetPath) is using $(FOO) notation rather than the
cmake ${FOO} notation. There is a large collection of these 'macros'
that you can access in custom commands when building under VS.

In our situation I just wanted to skip the copy step because there are
scenarios when it doesn't execute anyways and I wanted something like
this:

# Replacement for add_executable for servers
macro (add_server NAME)
        add_executable (${NAME} ${ARGN})
        set_target_properties (${NAME} PROPERTIES DEBUG_POSTFIX "_d")
        set_target_properties (${NAME} PROPERTIES
RUNTIME_OUTPUT_DIRECTORY ${ROOT}/servers/bin)
endmacro (add_server)

I found that the VS7 local generator doesn't honor the
*_OUTPUT_DIRECTORY properties so here's a modification that I added to
our local version:
