That's a good idea.
Nevertheless CMakeLists.txt is precisely the place where
OS specific features "CHECK" should be found :))

Yes I understand, nonetheless CPack IS a cross platform tools
just as CMake is.

I wrote  UseRPMTools such as it won't do anything (besides some checks)
if it is used on non-RPM aware build host.
If it not the case file me a bug :))

More precisely:
INCLUDE(CPack)
INCLUDE(UseRPMTools)

will ALWAYS succeed on any platform (even Windows)

Then you MUST check

  IF(RPMTools_FOUND)
     RPMTools_ADD_RPM_TARGETS(packagename)
  ENDIF(RPMTools_FOUND)

If for whatever reason RPMTools_FOUND is not set
to true by UseRPMTools you will not try
to build a RPM on a platform which is not supported.

Like I said,

you CMakeLists.txt and CMake MACRO used should be
robust on ANY platform, then using them appropriately
is not "really" OS-specific.

My opinion though :))
