# CMake passes command line flags like this:
# $compiler $lang_flags $lang_flags_config ...
# To ensure the flags tested here and elsewhere are obeyed a list of active
# build configuration types is built, and flags are applied to the flag strings
# for each configuration currently active for C and CXX builds as determined by
# reading $CMAKE_CONFIGURATION_TYPES and $CMAKE_BUILD_TYPE. When
# $CMAKE_CONFIGURATION_TYPES is non-empty a multi-configuration generator is in
# use: currently this includes MSVC and Xcode. For other generators
# $CMAKE_BUILD_TYPE is used. For both cases AOM_<LANG>_CONFIGS is populated with
# CMake string variable names that contain flags for the currently available
# configuration(s).
