INTERFACE_COMPILE_OPTIONS
-------------------------
List of interface options to pass to the compiler.
Targets may populate this property to publish the compile options
required to compile against the headers for the target. Consuming
targets can add entries to their own :prop_tgt:`COMPILE_OPTIONS` property
such as ``$<TARGET_PROPERTY:foo,INTERFACE_COMPILE_OPTIONS>`` to use the
compile options specified in the interface of ``foo``.
Contents of ``INTERFACE_COMPILE_OPTIONS`` may use "generator expressions"
with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)`
manual for available expressions. See the :manual:`cmake-buildsystem(7)`
manual for more on defining buildsystem properties.
