ISPCFLAGS
---------

.. versionadded:: 3.19

.. include:: ENV_VAR.txt

Default compilation flags to be used when compiling ``ISPC`` files. Will only be
used by CMake on the first configuration to determine ``ISPC`` default
compilation flags, after which the value for ``ISPCFLAGS`` is stored in the
cache as :variable:`CMAKE_ISPC_FLAGS <CMAKE_<LANG>_FLAGS>`. For any configuration
run (including the first), the environment variable will be ignored if
the :variable:`CMAKE_ISPC_FLAGS <CMAKE_<LANG>_FLAGS>` variable is defined.

See also :variable:`CMAKE_ISPC_FLAGS_INIT <CMAKE_<LANG>_FLAGS_INIT>`.
