# ISPC_HEADER_SUFFIX

Added in version 3.19.2.

Specify output suffix to be used for ISPC generated headers provided by the target.

This property is initialized by the value of the `CMAKE_ISPC_HEADER_SUFFIX` variable if it is set when a target is created.

If the target contains ISPC source files, this specifies the header suffix to be used for the generated headers.

The default value is `_ispc.h`.
