# INTERFACE_SOURCES

New in version 3.1.

List of interface sources to compile into consuming targets.

Targets may populate this property to publish the sources for consuming targets to compile. The `target_sources()` 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 sources of the consumer.

Contents of `INTERFACE_SOURCES` 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.
