MacOs installation issue. Libraries should be copied to bin.

[jgalan]

Recently we experienced some issues with make install not copying the restG4 binary and other components required. It seems the following PR #394 solved the problem.

That this is the case was confirmed at the following post at the rest-forum https://rest-forum.unizar.es/t/macos-installation-issue-missing-files-headers-bin/573/5

However, there are still some issues with some libraries (e.g. libRestRestG4.dylib) not being copied, as mentioned by @heucheld who states those libraries need to be copied to the bin directory.

Although I don't understand very much why those libraries should be at the bin directory we could create a condition for MacOs so that those libraries are installed to bin?

Perhaps we should understand better why those libraries need to be copied to bin and if this happens at any MacOs version.

I see that at the main CMakeLists.txt there is an exception for copying the files to the bin directory.

if (CMAKE_SYSTEM_NAME MATCHES "Darwin") # we must call library install here in
    # MacOs
    foreach (lib ${rest_libraries})
        install(
            TARGETS ${lib}
            RUNTIME DESTINATION bin
            LIBRARY DESTINATION bin
            ARCHIVE DESTINATION lib)
    endforeach ()

    foreach (exe ${rest_exes})
        install(
            TARGETS ${exe}
            RUNTIME DESTINATION bin
            LIBRARY DESTINATION bin
            ARCHIVE DESTINATION lib)
    endforeach ()

    # Copy pcm files to bin
    install(
        CODE "
    file(GLOB PCMFiles \"\${CMAKE_CURRENT_SOURCE_DIR}/rootdict/*.pcm\")
    file(COPY \${PCMFiles} DESTINATION \${CMAKE_INSTALL_PREFIX}/bin)
    ")

endif ()

Probably we need to add the exception somewhere else.
