Help/prop_tgt/INTERFACE_SOURCES.rst
.. versionadded:: 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 :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.
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.
