| CMP0000 |
| ------- |
| |
| A minimum required CMake version must be specified. |
| |
| CMake requires that projects specify the version of CMake to which |
| they have been written. This policy has been put in place so users |
| trying to build the project may be told when they need to update their |
| CMake. Specifying a version also helps the project build with CMake |
| versions newer than that specified. Use the cmake_minimum_required |
| command at the top of your main CMakeLists.txt file: |
| |
| :: |
| |
| cmake_minimum_required(VERSION <major>.<minor>) |
| |
| where "<major>.<minor>" is the version of CMake you want to support |
| (such as "2.6"). The command will ensure that at least the given |
| version of CMake is running and help newer versions be compatible with |
| the project. See documentation of cmake_minimum_required for details. |
| |
| Note that the command invocation must appear in the CMakeLists.txt |
| file itself; a call in an included file is not sufficient. However, |
| the cmake_policy command may be called to set policy CMP0000 to OLD or |
| NEW behavior explicitly. The OLD behavior is to silently ignore the |
| missing invocation. The NEW behavior is to issue an error instead of |
| a warning. An included file may set CMP0000 explicitly to affect how |
| this policy is enforced for the main CMakeLists.txt file. |
| |
| This policy was introduced in CMake version 2.6.0. |
