Per-configuration preprocessor definitions in a directory.

This is the configuration-specific version of COMPILE_DEFINITIONS where <CONFIG> is an upper-case name (ex. COMPILE_DEFINITIONS_DEBUG).

This property will be initialized in each directory by its value in the directory’s parent.

Contents of COMPILE_DEFINITIONS_<CONFIG> may use “generator expressions” with the syntax $<...>. See the cmake-generator-expressions(7) manual for available expressions. See the cmake-buildsystem(7) manual for more on defining buildsystem properties.

Generator expressions should be preferred instead of setting this property.
