May be in a specific separate file like CMakeScriptsDebuggingTools.cmake (or some less lengthy name) one may include ? > Or should this better be > message(VARIABLES CMAKE_C_COMPILER > CMAKE_MAJOR_VERSION > THIS_ONE_DOES_NOT_EXIST) Nope I wouldn't vote for that one. How would you print message(VARIABLES "BLAH " CMAKE_C_COMPILER) and message(VARIABLES "BLAH CMAKE_C_COMPILER") what you be nice as a built-in is something like trace_var(CMAKE_C_COMPILER) which would make the concerned VAR to be traced each time it is touched (read or written) by a script. That said we are far away from your initial need. and... I'm not volunteering to develop that :-( > Then I'll put it in extra-cmake-modules, but it seems to generic that I think > it makes sense to have it in cmake directly. -- Erk Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- Erk Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
