I use the attached file in order to build "SPECIFIC" system informations
like;

SPECIFIC_COMPILER_NAME  the name of the compiler used.
SPECIFIC_SYSTEM_VERSION_NAME the system version "name", WinXP, Debian,
SuSE etc...
SPECIFIC_SYSTEM_PREFERED_CPACK_GENERATOR the CPack that is "usually"
used on this specific system
 Debian or Ubuntu --> DEB, Windows --> NSIS, Fedora, RedHat, SuSE --> RPM etc...

For linux distros I use "lsb_release" if it is found or "/etc/issue"
as a fallback
may be you can pick-up some code in there.

The file is meant to be included in a CMakeLists.txt for which the
"project" command
has already been called.

Looks reasonable for me since I use similar feature.
