don't keep around those right-side fort files which are just mirror images of left-side forts. generate them at run-time instead. note: inlining changes and deleting files - so consider clean build/install

if(WIN32 AND NOT UNIX)
    file(GLOB DLLs *.dll)
    file(GLOB ICOs *.ico)

    install(FILES
        ${DLLs}
        ${ICOs}
        DESTINATION ${target_library_install_dir})
