CMAKE_PROJECT_HOMEPAGE_URL
|
||
|
|
--------------------------
|
||
|
|
|
||
|
|
The homepage URL of the top level project.
|
||
|
|
|
||
|
|
This variable holds the homepage URL 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_HOMEPAGE_URL`` contains. For example, consider
|
||
|
|
the following top level CMakeLists.txt:
|
||
|
|
|
||
|
|
.. code-block:: cmake
|
||
|
|
|
||
|
|
cmake_minimum_required(VERSION 3.0)
|
||
|
|
project(First HOMEPAGE_URL "http://first.example.com")
|
||
|
|
project(Second HOMEPAGE_URL "http://second.example.com")
|
||
|
|
add_subdirectory(sub)
|
||
|
|
project(Third HOMEPAGE_URL "http://third.example.com")
|
||
|
|
|
||
|
|
And ``sub/CMakeLists.txt`` with the following contents:
|
||
|
|
|
||
|
|
.. code-block:: cmake
|
||
|
|
|
||
|
|
project(SubProj HOMEPAGE_URL "http://subproj.example.com")
|
||
|
|
message("CMAKE_PROJECT_HOMEPAGE_URL = ${CMAKE_PROJECT_HOMEPAGE_URL}")
|
||
|
|
|
||
|
|
The most recently seen :command:`project` command from the top level
|
||
|
|
CMakeLists.txt would be ``project(Second ...)``, so this will print::
|
||
|
|
|
||
|
|
CMAKE_PROJECT_HOMEPAGE_URL = http://second.example.com
|
||
|
|
|
||
|
|
To obtain the homepage URL from the most recent call to :command:`project` in
|
||
|
|
the current directory scope or above, see the :variable:`PROJECT_HOMEPAGE_URL`
|
||
|
|
variable.
