When the Ubuntu package `libwxgtk3-dev` is not installed, FindwxWidgets
succeeds even the required libraries are not actually found. The reason
for that is that `wx-config` does not perform any kind of check and uses
hard-coded values. This affects e.g. KiCAD build process and makes it
fail with a confusing error message [1]. The solution is to check for
presence of every library file obtained from `wx-config`.

Latest wxWidgets git master version and the upcoming 3.1.1 release requires
linking with shlwapi and version DLLs. As this does no harm when using the
previous versions, just do it unconditionally.
The change in commit v3.7.0-rc1~217^2 (FindwxWidgets: Add VS-versioned
library directory prefixes, 2016-08-24) works only for official
wxWidgets builds that add the VS-versioned directory prefixes. Local
wxWidgets builds still have an unversioned prefix. Search them.
Closes: #16366
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names and years are hard to maintain and often out-of-date or plain wrong.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.
Add Visual Studio version number (supported: VS2008 to VS2015) to
WX_LIB_DIR_PREFIX (old: vc / vc_x64; new: vc120 / vc120_x64).

We use `sh wx-config` to launch the `wx-config` tool so that it can run
even on Windows. Since it is always a shell script its output may use
POSIX paths even on Windows. Use `cygpath` to convert to Windows paths.
This was added by commit v2.8.0~2292 (... Set variable
wxWidgets_INCLUDE_DIRS_NO_SYSTEM on the Mac ..., 2008-04-16) and updated
by commit v2.8.9~183^2 (FindwxWidgets: Do not use -isystem on OpenBSD,
2012-05-14). Since the underlying cause was never investigated fully we
do not know the conditions under which -isystem breaks wxWidgets, but
suppressing -isystem is problematic for users that do not want to see
warnings in wxWidgets headers. Simply drop the special case for now so
we can see whether anyone hits the problem again, at which point it can
be investigated in more detail.

The latter is now the preferred URL for visiting cmake.org with a
browser. Convert using the shell code:
git ls-files -z | xargs -0 sed -i 's|http://www\.cmake|https://cmake|g'
In commit v3.3.0-rc1~132^2 (FindwxWidgets: Search for wx-config-3.0 in
addition to wx-config, 2015-04-29) we added a second (versioned) name to
the find_program call. Specifying multiple names requires use of the
NAMES option. Add it now. While at it, also add versioned names for
2.9 and 2.8.
When compiling the 64 bit version of wxWidgets using nmake the library
folders become vc_x64_lib and vc_x64_dll and can coexist with the win32
version.
Instead of directly passing $ENV{SOMEVAR} to a find_* call pass in ENV SOMEVAR.
This will make sure the paths will get correctly handled through different
platforms, especially on Windows.
Also fixes one place where paths with windows delimiters (\) were hardcoded to
use forward slashes.
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |

The FindPackageHandleStandardArgs module was originally created outside
of CMake. It was added for CMake 2.6.0 by commit e118a627 (add a macro
FIND_PACKAGE_HANDLE_STANDARD_ARGS..., 2007-07-18). However, it also
proliferated into a number of other projects that at the time required
only CMake 2.4 and thus could not depend on CMake to provide the module.
CMake's own find modules started using the module in commit b5f656e0
(use the new FIND_PACKAGE_HANDLE_STANDARD_ARGS in some of the FindXXX
modules..., 2007-07-18).
Then commit d358cf5c (add 2nd, more powerful mode to
find_package_handle_standard_args, 2010-07-29) added a new feature to
the interface of the module that was fully optional and backward
compatible with all existing users of the module. Later commit 5f183caa
(FindZLIB: use the FPHSA version mode, 2010-08-04) and others shortly
thereafter started using the new interface in CMake's own find modules.
This change was also backward compatible because it was only an
implementation detail within each module.
Unforutnately these changes introduced a problem for projects that still
have an old copy of FindPackageHandleStandardArgs in CMAKE_MODULE_PATH.
When any such project uses one of CMake's builtin find modules the line
include(FindPackageHandleStandardArgs)
loads the copy from the project which does not have the new interface!
Then the including find module tries to use the new interface with the
old module and fails.
Whether this breakage can be considered a backward incompatible change
in CMake is debatable. The situation is analagous to copying a standard
library header from one version of a compiler into a project and then
observing problems when the next version of the compiler reports errors
in its other headers that depend on its new version of the original
header. Nevertheless it is a change to CMake that causes problems for
projects that worked with previous versions.
This problem was discovered during the 2.8.3 release candidate cycle.
It is an instance of a more general problem with projects that provide
their own versions of CMake modules when other CMake modules depend on
them. At the time we resolved this instance of the problem with commit
b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake
everywhere, 2010-09-28) for the 2.8.3 release.
In order to address the more general problem we introduced policy
CMP0017 in commit db44848f (Prefer files from CMAKE_ROOT when including
from CMAKE_ROOT, 2010-11-17). That change was followed by commit
ce28737c (Remove usage of CMAKE_CURRENT_LIST_DIR now that we have
CMP0017, 2010-12-20) which reverted the original workaround in favor of
using the policy. However, existing project releases do not set the
policy behavior to NEW and therefore still exhibit the problem.
We introduced in commit a364daf1 (Allow users to specify defaults for
unset policies, 2011-01-03) an option for users to build existing
projects by adding -DCMAKE_POLICY_DEFAULT_CMP0017=NEW to the command
line. Unfortunately this solution still does not allow such projects to
build out of the box, and there is no good way to suggest the use of the
new option.
The only remaining solution to keep existing projects that exhibit this
problem building is to restore the change originally made in commit
b0118402 (Use absolute path to FindPackageHandleStandardArgs.cmake
everywhere, 2010-09-28). This also avoids policy CMP0017 warnings for
this particular instance of the problem the policy addresses.
This puts the new search behaviour for included files in action, i.e.
now when a file from Modules/ include()s another file, it also gets the
one from Modules/ included, i.e. the one it expects.

Was not removing definition flags (-D...) from cxx flags,
when the definition flag was last in the list returned from
wx-config.

This allows the user not to link to the common libraries,
which are regularly required. The user must specify all
libraries that he does want to link in the find_package
line (png tiff jpeg zlib regex expat).

This adds copyright/license notification blocks CMake's find-modules.
Many of the modules had no notices at all. Some had notices referring
to the BSD license already. This commit normalizes existing notices and
adds missing notices.
