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 :command:`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 ``3.14``). 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 :command:`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 :command:`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. | |
