c9bea1ad62 Add initial support for CMake "Ninja Multi-Config" generator
This allows doing debug_and_release builds with Ninja on all
platforms.
The "Ninja Multi-Config generator" is available starting with CMake
3.17.

Desired configurations can be set via CMAKE_CONFIGURATION_TYPES.
Possible values: "Release, Debug, RelWithDebInfo, MinRelSize".
For example -DCMAKE_CONFIGURATION_TYPES="Release;Debug".

The first configuration is the 'default' configuration which is
built when calling ninja with no arguments.

To build all targets of a certain configuration use "ninja all:Release"
or "ninja all:Debug".

To build all targets in all configurations use "ninja all:all".

Note that the first configuration influences which configuration of
tools will be used when building the libraries for all configurations.
In simple terms, when configured with
-DCMAKE_CONFIGURATION_TYPES="Release;Debug" the release version of moc
is used by AUTOMOC.
When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release"
the debug version of moc is used by AUTOMOC.

Framework builds and Ninja Multi-Config don't currently work together
due to multiple bugs in CMake, which ends up generating an invalid ninja
file with duplicate rules. There are also issues with placement of the
debug artifacts.

This will be handled in a follow up patch after CMake is fixed.

38640f745e Fix toolchain path when doing non-prefix builds
Previously the cmake install prefix was added twice during a non-prefix
build, which evaluated to an incorrect path.

Set another absolute dir variable, and use that instead.

ffec6c7180 Add windows batch file for convenient cmake invocation with Qt toolchain file
Similar to the shell script, this makes it easier to invoke cmake by
just extending your PATH.
