# COMPILE_DEFINITIONS_<CONFIG>

Ignored. See CMake Policy `CMP0043`.

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.
