COMPILE_DEFINITIONS_ ---------------------------- Per-configuration preprocessor definitions on a target. This is the configuration-specific version of :prop_tgt:`COMPILE_DEFINITIONS` where ```` is an upper-case name (ex. ``COMPILE_DEFINITIONS_DEBUG``). Contents of ``COMPILE_DEFINITIONS_`` 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. Generator expressions should be preferred instead of setting this property.
