| CXXFLAGS |
| -------- |
| |
| .. include:: ENV_VAR.txt |
| |
| Default compilation flags to be used when compiling ``CXX`` (C++) files. Will |
| only be used by CMake on the first configuration to determine ``CXX`` default |
| compilation flags, after which the value for ``CXXFLAGS`` is stored in the cache |
| as :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>`. For any configuration run ( |
| including the first), the environment variable will be ignored if |
| the :variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` variable is defined. |
| |
| See also :variable:`CMAKE_CXX_FLAGS_INIT <CMAKE_<LANG>_FLAGS_INIT>`. |
