Raul Tambre 359c500a24 cmTarget: Raise error if imported target location is not set
Previously we would synthesize <TARGET_NAME>-NOTFOUND as the location. This
would then end up on the link line and cause build failures.
Policy CMP0110 is added to control this behaviour.

Fixes #19080, #19943.

CMP0111
-------
.. versionadded:: 3.19
An imported target with a missing location fails during generation.
Prior to this the location would be generated as ``<TARGET_NAME>-NOTFOUND``,
which would result in build failures.
The ``OLD`` behavior of this policy is to generate the location of an imported
unknown, static or shared library target as ``<TARGET_NAME>-NOTFOUND`` if not
set.
The ``NEW`` behavior is to raise an error.
This policy was introduced in CMake version 3.19. CMake version |release|
warns when the policy is not set and uses ``OLD`` behavior. Use the
:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
