Hi, I want to define a preprocessor directive through CMakeLists.txt, however the only documented method of doing this that I see is *add_definitions()*. Is there a better way of doing this? According to the documentation this isn't 100% portable, which in my opinion defeats the entire purpose of using CMake to begin with (Or at the very least that function itself). I don't think it is right to have to specify -D. I should be able to do:
add_definitions( BOOST_ALL_NO_LIB ) However, I have to do: add_definitions( -DBOOST_ALL_NO_LIB ) Any help would be greatly appreciated.
