How to create a C #define for a certain target using CMake?

Question

I feel a little stupid right now. After recently converting a few smaller projects to use CMake, I decided to also get rid of a few \"Platform_Config.h\" files. These files

Answer 1

option command might provide what you are looking for.
use it with the COMPILE DEFINITIONS property on the target and i think you are done. To set the property on the target, use the command set target properties

option(DEBUGPRINTS "Prints a lot of debug prints")
target(myProgram ...)
if(DEBUGPRINTS)
set_target_properties(myProgram PROPERTIES COMPILE_DEFINITIONS "DEBUGPRINTS=1")
endif()

edit:

The option i wrote in the example shows up as a checkbox in the CMake GUI.
