- 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.
