CMAKE_PROJECT_DESCRIPTION

CMAKE_PROJECT_DESCRIPTION

.. versionadded:: 3.9

The description of the top level project.

This variable holds the description 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_DESCRIPTION contains. For example, consider the following top level CMakeLists.txt:

.. code-block:: cmake

cmake_minimum_required(VERSION 3.0) project(First DESCRIPTION "I am First") project(Second DESCRIPTION "I am Second") add_subdirectory(sub) project(Third DESCRIPTION "I am Third")

And sub/CMakeLists.txt with the following contents:

.. code-block:: cmake

project(SubProj DESCRIPTION "I am SubProj") message("CMAKE_PROJECT_DESCRIPTION = ${CMAKE_PROJECT_DESCRIPTION}")

The most recently seen :command:project command from the top level CMakeLists.txt would be project(Second ...), so this will print::

CMAKE_PROJECT_DESCRIPTION = I am Second

To obtain the description from the most recent call to :command:project in the current directory scope or above, see the :variable:PROJECT_DESCRIPTION variable.
