Symbolic links CMake

Question

I want to rename certain executables in CMakeLists.txt but also want symbolic links from the older names to new files for backward compatibility. How can this b

Answer 1

I've struggled with this a few different ways with the above responses in order to install '.so.#' files that refer to other '.so.#.#' files. I've had success by not introducing a link to the file, but by installing the '.so.#.#' file as the '.so.#' file.

I.e. instead of

install(
    FILES
        .../libmpi.so.12.0
    DESTINATION lib
)

install(CODE 
    "EXECUTE_PROCESS( ${CMAKE_COMMAND} -E create_symlink lib/libmpi.so.12.0 lib/libmpi.so.12)")

Which didn't quite work for me even. I have instead had success by doing this.

install(FILES 
        .../libmpi.so.12.0
    RENAME libmpi.so.12
    DESTINATION lib
)

Not 'exactly' the same, but sufficient. Don't defeat the problem, solve the problem.
