Many environment variables were documented late and got assigned wrong versions by the script. (The whole Help/envvar section was only added in 3.10). Issue: #19715

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>`.
