.. which, at least according to my experiments, isn't possible it seems. However, also according to my experiments, `remove_definitions` doesn't actually remove macros defined by `add_compile_definitions` (only `add_definitions`), which brings up another question: Is this actually needed? Would it be sufficient to define _ALL_SOURCE as well?
