Thanks for working on this.  Some of the other find modules face
similar situation.  In order to avoid finding 64-bit binaries
when targeting a 32-bit architecture, use of such prefixes could
be guarded by

 if(CMAKE_SIZEOF_VOID_P EQUAL 8)

Please revise accordingly.  Also please check whether the
non-prefixed names should ever be used for 64-bit architectures.

Thanks,
