CMAKE_PROJECT_HOMEPAGE_URLΒΆ
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 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_HOMEPAGE_URL
contains. For example, consider
the following top level CMakeLists.txt:
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:
project(SubProj HOMEPAGE_URL "http://subproj.example.com")
message("CMAKE_PROJECT_HOMEPAGE_URL = ${CMAKE_PROJECT_HOMEPAGE_URL}")
The most recently seen 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 project()
in
the current directory scope or above, see the PROJECT_HOMEPAGE_URL
variable.
