1CMAKE_PROJECT_HOMEPAGE_URL 2-------------------------- 3 4.. versionadded:: 3.12 5 6The homepage URL of the top level project. 7 8This variable holds the homepage URL of the project as specified in the top 9level CMakeLists.txt file by a :command:`project` command. In the event that 10the top level CMakeLists.txt contains multiple :command:`project` calls, 11the most recently called one from that top level CMakeLists.txt will determine 12the value that ``CMAKE_PROJECT_HOMEPAGE_URL`` contains. For example, consider 13the following top level CMakeLists.txt: 14 15.. code-block:: cmake 16 17 cmake_minimum_required(VERSION 3.0) 18 project(First HOMEPAGE_URL "http://first.example.com") 19 project(Second HOMEPAGE_URL "http://second.example.com") 20 add_subdirectory(sub) 21 project(Third HOMEPAGE_URL "http://third.example.com") 22 23And ``sub/CMakeLists.txt`` with the following contents: 24 25.. code-block:: cmake 26 27 project(SubProj HOMEPAGE_URL "http://subproj.example.com") 28 message("CMAKE_PROJECT_HOMEPAGE_URL = ${CMAKE_PROJECT_HOMEPAGE_URL}") 29 30The most recently seen :command:`project` command from the top level 31CMakeLists.txt would be ``project(Second ...)``, so this will print:: 32 33 CMAKE_PROJECT_HOMEPAGE_URL = http://second.example.com 34 35To obtain the homepage URL from the most recent call to :command:`project` in 36the current directory scope or above, see the :variable:`PROJECT_HOMEPAGE_URL` 37variable. 38
