+
+Preferred executable for compiling ``ISPC`` language files. Will only be used by
+CMake on the first configuration to determine ``ISPC`` compiler, after which the
+value for ``ISPC`` is stored in the cache as
+:variable:`CMAKE_ISPC_COMPILER <CMAKE_<LANG>_COMPILER>`. For any configuration
+run (including the first), the environment variable will be ignored if the
+:variable:`CMAKE_ISPC_COMPILER <CMAKE_<LANG>_COMPILER>` variable is defined.

+---------
+
+.. 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>`.
