# INTERFACE_COMPILE_FEATURES

New in version 3.1.

List of public compile features requirements for a library.

Targets may populate this property to publish the compile features required to compile against the headers for the target. The `target_compile_features()` command populates this property with values given to the `PUBLIC` and `INTERFACE` keywords. Projects may also get and set the property directly.

When target dependencies are specified using `target_link_libraries()`, CMake will read this property from all target dependencies to determine the build properties of the consumer.

Contents of `INTERFACE_COMPILE_FEATURES` 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.

See the `cmake-compile-features(7)` manual for information on compile features and a list of supported compilers.
