.. versionadded:: 3.12
The version of the top level project.
This variable holds the version of the project as specified in the top
level CMakeLists.txt file by a :command:project command. In the event that
the top level CMakeLists.txt contains multiple :command:project calls,
the most recently called one from that top level CMakeLists.txt will determine
the value that CMAKE_PROJECT_VERSION contains. For example, consider
the following top level CMakeLists.txt:
.. code-block:: cmake
cmake_minimum_required(VERSION 3.0) project(First VERSION 1.2.3) project(Second VERSION 3.4.5) add_subdirectory(sub) project(Third VERSION 6.7.8)
And sub/CMakeLists.txt with the following contents:
.. code-block:: cmake
project(SubProj VERSION 1) message("CMAKE_PROJECT_VERSION = ${CMAKE_PROJECT_VERSION}")
The most recently seen :command:project command from the top level
CMakeLists.txt would be project(Second ...), so this will print::
CMAKE_PROJECT_VERSION = 3.4.5
To obtain the version from the most recent call to :command:project in
the current directory scope or above, see the :variable:PROJECT_VERSION
variable.
