INTERFACE_INCLUDE_DIRECTORIES
-----------------------------

List of public include directories for a library.

Targets may populate this property to publish the include directories
required to compile against the headers for the target.  Consuming
targets can add entries to their own INCLUDE_DIRECTORIES property such
as $<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES> to use the
include directories specified in the interface of 'foo'.

This property also supports generator expressions.  See the
:manual:`cmake-generator-expressions(7)` manual for available expressions.
