CMAKE_PROJECT_DESCRIPTIONΒΆ
Added in version 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 project()
command. In the event that
the top level CMakeLists.txt contains multiple 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:
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:
project(SubProj DESCRIPTION "I am SubProj")
message("CMAKE_PROJECT_DESCRIPTION = ${CMAKE_PROJECT_DESCRIPTION}")
The most recently seen 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 project()
in
the current directory scope or above, see the PROJECT_DESCRIPTION
variable.
