CMP0084 — CMake 3.24.1 Documentation

# CMP0084

New in version 3.14.

The `FindQt` module does not exist for `find_package()`.

The existence of `FindQt` means that for Qt upstream to provide package config files that can be found by `find_package(Qt)`, the consuming project has to explicitly specify `find_package(Qt CONFIG)`. Removing this module gives Qt a path forward for exporting its own config files which can easily be found by consuming projects.

This policy pretends that CMake's internal `FindQt` module does not exist for `find_package()`. If a project really wants to use Qt 3 or 4, it can call `find_package(Qt[34])`, `include(FindQt)`, or add `FindQt` to their `CMAKE_MODULE_PATH`.

The `OLD` behavior of this policy is for `FindQt` to exist for `find_package()`. The `NEW` behavior is to pretend that it doesn't exist for `find_package()`.

This policy was introduced in CMake version 3.14. CMake version 3.24.1 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.
