Remove basic CPS import and export from 'experimental' status. Update documentation and tests accordingly. Note that mapped exports (CMAKE_EXPERIMENTAL_MAPPED_PACKAGE_INFO) are still experimental.

CMAKE_PROJECT_COMPAT_VERSION
|
|
----------------------------
|
|
|
|
.. versionadded:: 4.3
|
|
|
|
The compatibility version of the top level project.
|
|
|
|
This variable holds the compatibility version 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_COMPAT_VERSION`` contains. For
|
|
example, consider the following top level CMakeLists.txt:
|
|
|
|
.. code-block:: cmake
|
|
|
|
cmake_minimum_required(VERSION 4.3)
|
|
project(First VERSION 9.0 COMPAT_VERSION 1.2.3)
|
|
project(Second VERSION 9.0 COMPAT_VERSION 3.4.5)
|
|
add_subdirectory(sub)
|
|
project(Third VERSION 9.0 COMPAT_VERSION 6.7.8)
|
|
|
|
And ``sub/CMakeLists.txt`` with the following contents:
|
|
|
|
.. code-block:: cmake
|
|
|
|
project(SubProj VERSION 2.0 COMPAT_VERSION 1.0)
|
|
message("CMAKE_PROJECT_COMPAT_VERSION = ${CMAKE_PROJECT_COMPAT_VERSION}")
|
|
|
|
The most recently seen :command:`project` command from the top level
|
|
CMakeLists.txt would be ``project(Second ...)``, so this will print::
|
|
|
|
CMAKE_PROJECT_COMPAT_VERSION = 3.4.5
|
|
|
|
To obtain the version from the most recent call to :command:`project`
|
|
in the current directory scope or above, see the
|
|
:variable:`PROJECT_COMPAT_VERSION` variable.
