ISPC — CMake 3.30.5 Documentation

# ISPC

New in version 3.19.

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

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 `CMAKE_ISPC_COMPILER`. For any configuration run (including the first), the environment variable will be ignored if the `CMAKE_ISPC_COMPILER` variable is defined.
