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.
