Add compile definitions to a target.

  [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])

Specify compile definitions to use when compiling a given <target>. The named <target> must have been created by a command such as add_executable() or add_library() and must not be an Imported Target.

The INTERFACE, PUBLIC and PRIVATE keywords are required to specify the scope of the following arguments. PRIVATE and PUBLIC items will populate the COMPILE_DEFINITIONS property of <target>. PUBLIC and INTERFACE items will populate the INTERFACE_COMPILE_DEFINITIONS property of <target>. The following arguments specify compile definitions. Repeated calls for the same <target> append items in the order called.

Arguments to target_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.
