# INTERFACE_PRECOMPILE_HEADERS

List of interface header files to precompile into consuming targets.

Targets may populate this property to publish the header files for consuming targets to precompile. The `target_precompile_headers()` command populates this property with values given to the `PUBLIC` and `INTERFACE` keywords. Projects may also get and set the property directly. See the discussion in `target_precompile_headers()` for guidance on appropriate use of this property for installed or exported targets.

Contents of `INTERFACE_PRECOMPILE_HEADERS` may use “generator expressions” with the syntax `$<...>`. See the `cmake-generator-expressions(7)` manual for available expressions. See the `cmake-buildsystem(7)` manual for more on defining buildsystem properties.
