COMPILE_DEFINITIONS_ ---------------------------- .. deprecated:: 3.0 Prefer the :prop_sf:`COMPILE_DEFINITIONS` source-file property with :manual:`generator expressions `. Per-configuration preprocessor definitions on a source file. This is the configuration-specific version of :prop_sf:`COMPILE_DEFINITIONS`. Note that :generator:`Xcode` does not support per-configuration source file flags so this property will be ignored by the :generator:`Xcode` generator.
