Subject: [PATCH 18/19] CMakeLists.txt: Use GNU installation paths

The GNUInstallDirs macro makes it possible for the user to override the
destination paths for library and headers. It also automatically
installs to lib64/ if that's the distro default.

The installation components are marked in case someone makes a CPack
installer.
