INTERFACE_SOURCES

Added 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.
