INTERFACE_SOURCES ----------------- List of interface sources to compile into consuming targets. Targets may populate this property to publish the sources for consuming targets to compile. The :command:`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 :command:`target_link_libraries`, CMake will read this property from all target dependencies to determine the sources of the consumer. Targets with ``INTERFACE_SOURCES`` may not be exported with the :command:`export` or :command:`install(EXPORT)` commands. This limitation may be lifted in a future version of CMake. Contents of ``INTERFACE_SOURCES`` may use "generator expressions" with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` manual for available expressions. See the :manual:`cmake-buildsystem(7)` manual for more on defining buildsystem properties.
