COMPILE_OPTIONS --------------- List of options to pass to the compiler. This property specifies the list of options given so far to the :command:`add_compile_options` command. This property is used to populate the :prop_tgt:`COMPILE_OPTIONS` target property, which is used by the generators to set the options for the compiler. Contents of ``COMPILE_OPTIONS`` may use "generator expressions" with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)` manual for available expressions. See the :manual:`cmake-buildsystem(7)` manual for more on defining buildsystem properties.
