I just realized another reason why your proposal is not adequate: the
libraries and the script must be built before the executable, so, at
cmake time, the libraries and the script does not exists.

I know this is not portable, but it is intended for POSIX platforms, GNU
toolchains. As far as cmake does not mess too much with the contents
passed to target_link_libraries, it should be fine.
