How to define preprocessor definition for each configuration in CLion?

Question

I have several build profiles in CLion -> Settings -> Build, Execution, Deployment -> CMake. How can I set the preprocessor definitions for each profile, regardless of which compiler I use?

Answer 1

1. Go to Settings -> Build, Execution, Deployment -> CMake.
2. Select the profile for which you want to set preprocessor definition.
3. Write in the CMake options field: -DYOUR_DEFINE_VARIABLE=1
4. In your CMakeLists.txt write the following:

if (YOUR_DEFINE_VARIABLE)
    add_definitions(-DYOUR_DEFINE_VARIABLE=1)
endif (YOUR_DEFINE_VARIABLE)
