See the :manual:`cmake-generator-expressions(7)` manual for available expressions. See the :manual:`cmake-buildsystem(7)` manual for more on defining buildsystem properties. + +Include directories usage requirements commonly differ between the build-tree +and the install-tree. The ``BUILD_INTERFACE`` and ``INSTALL_INTERFACE`` +generator expressions can be used to describe separate usage requirements +based on the usage location. Relative paths are allowed within the +``INSTALL_INTERFACE`` expression and are interpreted relative to the +installation prefix.
