[CMake] Setting Policy CMP0028

[pierre.andersson at se.atlascopco.com]

Then it is odd that it does not work, the warning is given during
generation time and I have tested to print the status of the 0028 policy at
all points where the projects that get the warning has their
add_library/add_executable command called, as well as at the end of their
respective CMakeLists.txt files and it remains in the state OLD throughout.
At which point is the state of the policy stored when it comes to
generation time? I can see that it works when I construct a minimal
example, so knowing when it's state is 'used' would greaty help in solving
the issue or creating a minimal example that showcases the problem.

Regards,
Pierre Andersson

You can not change policies for the parent; only for the current and
subdirectories.

It might help if you could create a minimal, selfcontained test case to
reproduce and debug the issue.
