Install .cmake files in CMAKE_INSTALL_LIBDIR

This avoid problems when build and install 64 and 32 bits libs at same time,
because both overwrite the .cmake files if install it in an non-architecture depend path
like is `share/cmake/foo` is.

cmake now pick the correct .cmake files when try to add to another project as depencies
