The :command:`project` command preserves leading zeros in version components.
|
||
|
|
|
||
|
|
When a ``VERSION <major>[.<minor>[.<patch>[.<tweak>]]]]`` argument is given
|
||
|
|
to the :command:`project` command, it stores the version string in the
|
||
|
|
``PROJECT_VERSION`` variable and stores individual integer version components
|
||
|
|
in ``PROJECT_VERSION_{MAJOR,MINOR,PATCH,TWEAK}`` variables (see policy
|
||
|
|
:policy:`CMP0048`). CMake 3.15 and below dropped leading zeros from each
|
||
|
|
component. CMake 3.16 and higher prefer to preserve leading zeros. This
|
||
|
|
policy provides compatibility for projects that have not been updated to
|
||
|
|
expect the new behavior.
|
||
|
|
|
||
|
|
The ``OLD`` behavior of this policy drops leading zeros in all components,
|
||
|
|
e.g. such that version ``1.07.06`` becomes ``1.7.6``. The ``NEW`` behavior
|
||
|
|
of this policy preserves the leading zeros in all components, such that
|
||
|
|
version ``1.07.06`` remains unchanged.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.16. Unlike many policies, CMake
|
||
|
|
version |release| does *not* warn when this policy is not set and simply uses
|
||
|
|
the ``OLD`` behavior. Use the :command:`cmake_policy` command to set it to
|
||
|
|
``OLD`` or ``NEW`` explicitly.
