[CMake] POST_BUILD in a different directory

[Andreas Pokorny]

Hello,
I have the same requirement. I would like to attach copy commands to targets
built in different directories. I want to copy dlls/pdb/so -files into
other directories
that contain test cases which are supposed to use the libraries.

I have a "clean" solution that only works in NMake and gnumake. The macro
that creates the test cases, creates a new target and attaches all
copy commands
to that target, by specifying a dependencies two the original library,
the copy command
will be executed everytime the library changes.

ADD_CUSTOM_TARGET(Dummy ALL)

ADD_CUSTOM_COMMAND(TARGET Dummy
                        POST_BUILD
                        COMMAND ${CMAKE_COMMAND} -E copy
                        ${__COPY_SOURCE_PATH}/${LIBNAME}.dll
                        ${__COPY_DEST_PATH}
                        DEPENDS ${__COPY_SOURCE_PATH}/${LIBNAME}.dll
                        )

The dummy target exists within each cmake project that calls the
macro. But with
Visual Studio the project names must be unique. So only the first one
is loaded :(.

To solve that issue the "dirty" solution ensures that the dummy target
is created from
the project name, so the target and project file will be unique.

ADD_CUSTOM_TARGET(${PROJECT_NAME}_Dummy ALL)
ADD_CUSTOM_COMMAND(TARGET ${PROJECT_NAME}_Dummy
                        POST_BUILD
                        COMMAND ${CMAKE_COMMAND} -E copy
                        ${__COPY_SOURCE_PATH}/${LIBNAME}.dll
                        ${__COPY_DEST_PATH}
                        DEPENDS ${__COPY_SOURCE_PATH}/${LIBNAME}.dll
                        )



kind regards
Andreas
