Torsten Rasmussen b574c4f626 cmake: check zephyr version if specified and ZEPHYR_BASE is set
Fixes: #35187

This extends the Zephyr package to also honor version when ZEPHYR_BASE
is set in environment.

Specifying `find_package(Zephyr 2.x.y)` without using ZEPHYR_BASE will
lookup a Zephyr in following order:
- Current repo, if that is a Zephyr repo
- Current west workspace
- Exported Zephyr CMake package for freestanding application
and ensure that the chosen Zephyr meets the version criteria.

When setting ZEPHYR_BASE in environment the version check is disabled
and the Zephyr referenced by ZEPHYR_BASE will always be used regardless
of its version.

A user doing `find_package(Zephyr 2.6.0)` and using ZEPHYR_BASE
presumable still want to ensure that the Zephyr referenced by
ZEPHYR_BASE is v2.6.0 or newer.

Also, `west build` with a freestanding application requires ZEPHYR_BASE
in order for west to lookup the `west build` extension command.

This practically means a user cannot both specify a Zephyr version for a
freestanding application and at the same time use `west build` but has
to use plain CMake to ensure correct version check, see #35187.

With this commit, users will have complete Zephyr package version
checking with freestanding applications
find_package(Zephyr 2.6.0 REQUIRED HINTS $ENV{ZEPHYR_BASE})
find_package(Zephyr 2.6.0 EXACT REQUIRED HINTS $ENV{ZEPHYR_BASE})
when also having ZEPHYR_BASE in environment.

This commit has no behavioral change for those patterns:
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
find_package(Zephyr 2.6.0 REQUIRED HINTS $ENV{ZEPHYR_BASE})
find_package(Zephyr 2.6.0 EXACT REQUIRED HINTS $ENV{ZEPHYR_BASE})
when ZEPHYR_BASE is not in environment.

Torsten Rasmussen fe5728dcb0 cmake: using MD5_INFILE variable instead of ZephyrPackagePath.txt
Running `west zephyr-export` creates an entry in the CMake User package
registry.

During this process, a temporary file `current_path.txt` is created.

This commit ensure the file is removed when no longer needed.

Torsten Rasmussen edde894d04 cmake: Zephyr CMake package clean-up and minor fix
Fixes: #27375

This is a cleanup of the Zephyr CMake package export.
The code has been simplified so that the export now happens through a
CMake script. This avoids several generated CMake build files compared
to previous export mode, and thus removes the need for a CMake pristine
script.

A benefit of this cleanup is that it also fixes #27375.

Torsten Rasmussen 4c28016e43 cmake: fixing infinite loop when searching for Zephyr on windows
Fixes: #24909

This commit compares against previous search path instead of '/'.
This fixes the infinite loop issue on windows when building a Zephyr
standalone application and not setting ZEPHYR_BASE.

Torsten Rasmussen 3074a7a498 cmake: Relocating Zephyr Unittest CMake package.
Fixes: #23872

Relocating Zephyr Unittest CMake package to ensure that
HINTS ${ZEPHYR_BASE} in
find_package(ZephyrUnittest HINTS ${ZEPHYR_BASE}) works correctly when
the package has not been exported to CMake user package registry.

This ensure that the new package functionality is fully backwards
compatible on systems where the package is not exported and ZEPHYR_BASE
is set.

Torsten Rasmussen 8e929fd20c cmake: find_package to honor list of zephyr installations to prefer
This commit introduces ZEPHYR_PREFER which is a list that user can
specify when compiling an application.

This allows a user who has multiple Zephyr installations in the same
work-tree to provide a list of which Zephyr to prefer.

This is an extension to CMake VERSION field, as a user who is working
with multiple Zephyr installations could face a situation where multiple
Zephyr's is having same version, as example 2.2.99, in which case CMake
version is not sufficient.

Example, workspace looking as:
/projects/workspace/zephyr
/projects/workspace/zephyr-alternate
/projects/workspace/zephyr-wip
/projects/workspace/my_app

To prefer zephyr-alternate, then zephyr-wip the my_app/CMakeLists.txt
should look as:
set(ZEPHYR_PREFER "zephyr-alternate" "zephyr-wip")
find_package(Zephyr)

Torsten Rasmussen 3dd96d8927 cmake: Added possibility to disable the printing of version
When ZephyrConfig package is being version checked, then
ZephyrConfigVersion.cmake loads version.cmake.

This causes a print message, such as the following to happen:
-- Zephyr version: 2.2.0

Now, in case a user has multiple Zephyr installations, this could
result in something similar to:
-- Zephyr version: 2.2.0
-- Zephyr version: 2.x.0
-- Zephyr version: 3.x.0
being printed.

This commit add the possibility to disable version printing.

With new Zephyr base find_package, printing of ZEPHYR_BASE is added
after the version, in order to make it easy for users to see which
Zephyr is used.

Torsten Rasmussen 81007172a4 cmake: adding ZephyrConfig.cmake to allow an easy way to locate Zephyr
Adding ZephyrConfig.cmake and ZephyrConfigVersion.cmake allows projects
to use find_package to locate Zephyr.

This means that it will be possible to allow users to run CMake without
the need to source zephyr-env.sh or run zephyr-env.cmd.

This is especially useful for IDEs such as Eclipse or SES, where it will
no longer be required to source the above files before launching the
IDE.
