# INTERFACE_COMPILE_DEFINITIONS

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.
