CMP0145 — CMake 3.28.3 Documentation

# CMP0145

New in version 3.27.

The `Dart` and `FindDart` modules are removed.

These modules were added very early in CMake's development to support driving tests with a "DART" tool, but DART has not been distributed or maintained for many years. Projects would `include(Dart)` to use it, and the `Dart` module would run `find_package(Dart)` internally. Since `ctest(1)` was created, the `Dart` module has just been a compatibility shim that finds `Dart` to support some legacy functionality and then forwards to the `CTest` module.

CMake 3.27 and above prefer to not provide the `Dart` or `FindDart` modules. This policy provides compatibility for projects that have not been ported away from them. Projects using the `Dart` module should be updated to use the `CTest` module directly.

The `OLD` behavior of this policy is for `include(Dart)` and `find_package(Dart)` to load the deprecated modules. The `NEW` behavior is for uses of the modules to fail as if they do not exist.

This policy was introduced in CMake version 3.27. CMake version 3.28.3 warns when the policy is not set and uses `OLD` behavior. Use the `cmake_policy()` command to set it to `OLD` or `NEW` explicitly.

Note

The `OLD` behavior of a policy is `deprecated by definition` and may be removed in a future version of CMake.
