+COMPILE_OPTIONS
+---------------
+
+List of additional options to pass to the compiler.
+
+This property holds a :ref:`;-list <CMake Language Lists>` 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.
+
+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.
