# So there is a problem:
# 1. Number of these symbols only grows, as we support more and more ports
# 2. CMake was written by morons and can't check these symbols in parallel
# 3. MSVC is very slow at everything (startup, parsing, generating error)

# Solution: group these symbols and set variable if one of them was found
# this way we can reorder to reorder them by most common configurations
# but we can't generate this list anymore! ... OR IS IT ???

# Well, after reordering positions in engine's buildenums.h, we can partially autogenerate this list!
