COMPILE_OPTIONS --------------- List of additional options to pass to the compiler. This property holds a :ref:`semicolon-separated list ` of options and will be added to the list of compile flags when this source file builds. Use :prop_sf:`COMPILE_DEFINITIONS` to pass additional preprocessor definitions and :prop_sf:`INCLUDE_DIRECTORIES` to pass additional include directories. Contents of ``COMPILE_OPTIONS`` may use "generator expressions" with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` manual for available expressions. However, :generator:`Xcode` does not support per-config per-source settings, so expressions that depend on the build configuration are not allowed with that generator. .. note:: This property should be preferred over the :prop_sf:`COMPILE_FLAGS` property.
