Add the `NAMES_PER_DIR` option to our `find_library` call so that all
names are considered in each path as we proceed through the search.
This allows locally-built unversioned libraries to be found before
versioned system libraries if they appear earlier in the set of paths to
be searched.

Code added by commit v3.12.0-rc1~53^2 (FindLua: Search for lua.h using
more conventional paths, 2018-05-20) depends on `CMP0012` NEW behavior.
Set the policy explicitly for the scope of the FindLua module.
Fixes: #18142
Do not constrain the search to `include/*`. To provide compatibility
the foreach-loop is still used. However `include/xxx` and `xxx` is now
both searched. This honors now e.g. CMAKE_INCLUDE_PATH.
Fixes: #17999
We use `LUA_INCLUDE_PREFIX` for the result of an internal `find_path`
call and unset the cache entry before each use. Unset a plain variable
of this name too in case it was set by project code. Otherwise the
`find_path` call may be skipped and the wrong value used, leading to
errors.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
