If I could, I would have done it since 2.8.4-RC1 ;-) Basically, we call several CMake projects from the same shell scripts, and each CMake invokation receive the same set of global parameters. The same way you can invoke a compiler with several -D options and safely ignore the definitions you do not care about. Or the same way you can place as many variables as you want in the environment and let a program decides whether it "wants" to use it or not. I'm looking for the same feature for CMake. I used to do it with -D option switch, it seems I can't do it anymore. > The other option is simply to ignore all of our "was not used" output. > They are only warnings.

False warnings simply distract the developer that have no choice but start ignoring them - and fail to detect real and useful ones. > I guess I don't understand your "big picture" here.

I'm just looking to invoke CMake with a set of variables, some of which being useful for a given CMake script, some others being safely ignored - as they used to be, BTW. How to do this? "make" accepts a random list of definitions: make key1=value1 key2=value2 ... "gcc" accepts a random list of definitions: gcc -DKEY1=value1 -DKEY2=value2 What is the equivalent way of passing such arguments to a CMake script ? Thanks Emmanuel. _______________________________________________ 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://www.cmake.org/mailman/listinfo/cmake
