Summary:                    cmake miss --rapth-link when bin/c++ and
lib/libfoo.so are in same directory
Description: 
When linking an executable with a library `libfoo.so` that depedent on a library
`libbar.so` in a non standard directory, flag `-Wl,-rpath-link=...` is required
so that `ld` can find `libar.so`.

It works well with /usr/bin/gcc and libraries somewhere in a non standard
directory, CMake uses the flag `-Wl,-rpath-link`.

But in this case:
    /path/to/somewhere/bin/gcc
    /path/to/somewhere/lib/libfoo.so
    /path/to/somewhere/lib/libbar.so

and with /path/to/somewhere/bin in the PATH, without setting LD_LIBRARY_PATH,
CMake drops the flag `-Wl,-rpath-link=...` and the build fails.
