The latest version of MSVC STL brings C++23 standard library modules, which conflict with precompiled headers.
Disabling with /experimental:module- has no effect, so force C++20 in the meantime while we wait for module support in other compilers.
Currently the exported version of lz4 provided by vcpkg is malformed and
is "unknown". This makes querying for a specific version broken.
Fixes configuring CMake with the use of vcpkg.
Uses find_package_handle_standard_args to handle the find_package call
from the root CMakeLists. Removes all the unnecessary logic after the
find_package and just sets it to REQUIRED.
This PR rearranges things in the CMake system to make compiling with Qt6 possible
1. Camera API has changed in Qt6, so the camera feature is disabled
2. A previous fix involving QLocale is now version gated.
3. QRegExp replaced with QRegularExpression, see #5343
4. Qt6_LOCATION option added to specify a location to search for Qt6
(see examples below)
5. windeployqt is used to copy Qt6 files into the build directory on Windows
Notes for Arch Linux
Arch install happened to have qt6-base qt6-declarative qt6-translations installed
mkdir build && cd build
cmake .. -GNinja -DYUZU_USE_BUNDLED_VCPKG=ON -DYUZU_TESTS=OFF -DENABLE_QT6=YES -DYUZU_USE_BUNDLED_QT=NO

Qt wants users to download precompiled libraries via an online installer,
it is worth noting that the GPL/LGPL takes precendence over any ...
In the Qt Maintenance tool, under a version, such as 6.3.1
Select "MSVC 2019 64-bit"
Under Additional Libraries Qt Multimedia may be of use for Camera support
For the Web Applet I had to select the following:
