The :command:`target_include_directories(SYSTEM)` +command signature populates this property with values given to the +``PUBLIC`` and ``INTERFACE`` keywords. + +Projects may also get and set the property directly, but must be aware that +adding directories to this property does not make those directories used +during compilation. Adding directories to this property marks directories +as ``SYSTEM`` which otherwise would be used in a non-``SYSTEM`` manner. This +can appear similar to 'duplication', so prefer the +high-level :command:`target_include_directories(SYSTEM)` command and avoid +setting the property by low-level means. + +When target dependencies are specified using :command:`target_link_libraries`, +CMake will read this property from all target dependencies to mark the +same include directories as containing system headers. + +Contents of ``INTERFACE_SYSTEM_INCLUDE_DIRECTORIES`` 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. |
