List of public compile definitions for a library.

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

Contents of INTERFACE_COMPILE_DEFINITIONS may use “generator expressions” with the syntax $<...>. See the cmake-generator-expressions(7) manual for available expressions. See the cmake-buildsystem(7) manual for more on defining buildsystem properties.
