ISPC_HEADER_DIRECTORY — CMake 4.3.3 Documentation

# ISPC_HEADER_DIRECTORY

Added in version 3.19.

Specify relative output directory for ISPC headers provided by the target.

If the target contains ISPC source files, this specifies the directory in which the generated headers will be placed. Relative paths are treated with respect to the value of `CMAKE_CURRENT_BINARY_DIR`. When this property is not set, the headers will be placed a generator defined build directory. If the variable `CMAKE_ISPC_HEADER_DIRECTORY` is set when a target is created its value is used to initialize this property.
