CMake: install to correct lib dir (#93)

64-bit libraries should be installed in /usr/lib64, not in /usr/lib/
Make the destination lib dir configurable.

Commit e13e72e17692f5dc0036460d734c637b563f3ac7 removed
include(GNUInstallDirs) and ${CMAKE_INSTALL_LIBDIR} which broke
installing on 64-bit systems.
