i'm very bad explaining this so i'll try to say with way too, first an example, we have a foo project with a fuu-1 and fuu-2 preprocessor options, so if we want compile the project we do: cmake . -Dfuu-1=ON -Dfuu-2=ON if we need both options, and then we do make and the project is compiled, but if we want try other like cmake . -Dfuu-1=ON -Dfuu-2=OFF the project recompile the files with the modified preprocessor. So the idea, first compile the project without the preprocessor options, then as second phase compile with the options, so if we change some option when we use make the compiler skip the first phase and only compile the preprocessor options. sorry my bad eng. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2015-10-27 16:52 Lagu New Issue ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
