Summary0015719: cmake miss --rapth-link when bin/c++ and lib/libfoo.so are in same directory
DescriptionWhen 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.

Maybe the problem is that the directory containing libbar.so is in `gcc -print-search-dirs`, and CMake wrongly assumes that this directory is search by ld too.
