I think it would be good to still use libgcrypt-config if it finds it and can run it to provide hints to find_library and find_path (in much the same way pkg-config is used for other find modules).

Just to note that if you want to submit it to ECM (which I think is probably a good idea), you'll need to provide an imported target as well.


cmake/FindLibGcrypt.cmake

    Have a look at FindEGL.cmake in ECM master for what I view as a better documentation style (although that's only something I'm going to demand if you submit it to ECM).

    The license should be separated from the docs by a completely blank line (no #). Also, (c) is pointless in copyright statements.



cmake/FindLibGcrypt.cmake

    Please put in the full license (BSD 3-clause).



cmake/FindLibGcrypt.cmake

    This shouldn't be here (unless the find module really can't deal with older versions).
