# Different configuration types:
#
# Custom : User specify flags with CMAKE_C_FLAGS and CMAKE_CXX_FLAGS
# Debug : Optimized for debugging, include debug symbols
# Release : Release mode, no debuginfo
# RelWithDebInfo : Distribution mode, basic optimizations for portable code with debuginfos
# Fast : Maximum level of optimization. Target native architecture, not portable code
# FastDebug: Similar to Debug with a bit higher level optimisations (-O1) and other compiler
# flags so that it's faster than -O0 but still produces consistent results for
# testing and debugging purposes.
