CMAKE_CONFIGURATION_TYPES — CMake 3.30.5 Documentation

# CMAKE_CONFIGURATION_TYPES

Specifies the available build types (configurations) on multi-config generators (e.g. Visual Studio, `Xcode`, or `Ninja Multi-Config`) as a semicolon-separated list. Typical entries include `Debug`, `Release`, `RelWithDebInfo` and `MinSizeRel`, but custom build types can also be defined.

This variable is initialized by the first `project()` or `enable_language()` command called in a project when a new build tree is first created. If the `CMAKE_CONFIGURATION_TYPES` environment variable is set, its value is used. Otherwise, the default value is generator-specific.

Depending on the situation, the values in this variable may be treated case-sensitively or case-insensitively. See Build Configurations for discussion of this and other related topics.

For single-config generators, see `CMAKE_BUILD_TYPE`.
