| Summary | 0016069: Behaviour does not match documentation for policy CMP0048 | ||||||||
| Description | The policy documentation for CMP0048 says this: "This policy was introduced in CMake version 3.0. CMake version 3.5.2 warns when the policy is not set and uses OLD behavior. Use the cmake_policy command to set it to OLD or NEW explicitly." In my testing, however, no such warning is issued and the default appears to be NEW, not OLD. | ||||||||
| Steps To Reproduce | The following minimal CMakeLists.txt demonstrates the problem: cmake_minimum_required(VERSION 3.5.2) cmake_policy(GET CMP0048 isOn) message("isOn = ${isOn}") project(proj VERSION 1.2.3) Changing the minimum required version doesn't seem to make any difference. | ||||||||
| Additional Information | If you explicitly set the policy for CMP0048 to OLD, then the expected error does occur when the project() command includes a VERSION specification. | ||||||||

The call to cmake_minimum_required(VERSION): https://cmake.org/cmake/help/v3.5/command/cmake_minimum_required.html [^] implies a call to cmake_policy(VERSION) which sets the policy to NEW because the min req version specified is at least 3.0. Once the policy is set the NEW behavior is used without any warning. |

For reference, this behavior of cmake_minimum_required has been clarified in post-3.5 documentation updates: Help: Organize and clarify `cmake_minimum_required` documentation https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=1dc8486b [^] |
