Subject: [PATCH] Do not assume /usr/lib library installation.

Current `pkgconfig` configuration file installation path and its
contents assume libraries are installed under `/usr/lib` and this is not
always the case, for instance `/usr/lib64` is quite possible under
Gentoo Linux.

Thus use the `CMAKE_INSTALL_LIBDIR` variable instead of a hardcoded
`lib`.
