An imported target with a missing location fails during generation.
An imported target missing its location property fails during generation.
Prior to this the location would be generated as ``<TARGET_NAME>-NOTFOUND``,
which would result in build failures.
:ref:`Imported Targets` for library files and executables require that
their location on disk is specified in a target property such as
:prop_tgt:`IMPORTED_LOCATION`, :prop_tgt:`IMPORTED_IMPLIB`, or a
per-configuration equivalent. If a needed location property is not set,
CMake 3.18 and below generate the string ``<TARGET_NAME>-NOTFOUND`` in
its place, which results in failures of the corresponding rules at build
time. CMake 3.19 and above prefer instead to raise an error during
generation. This policy provides compatibility for projects that have
not been updated to expect the new behavior.
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
