Well, yes, but a few minor notes here:

  * the upstream has to use GNUInstallDirs module
  * it will not work for arch-dependent include dir, because it is set
    to "include" always
  * the final variables are called CMAKE_INSTALL_* where asterisk
    is one of many names (LIBDIR, INCLUDEDIR, etc.)

Cheers,
