Port the build system of the qtquickdesigner-components to CMake.
This is the repository we use for the studio controls and other Qt Design Studio specific components. The current build system is still based on qmake.
We should also make qmakefiles.txt that build the repository.
The QML modules are installed into the QML folder of the Qt that builds the repository.
When the cmakefiles.txt from the root folder is opened in Qt Creator,
the project is configured with cmake and build then it should be installed into
the Qt QML folder, like currently with qmake.
We should follow what Qt does for e.g. Qt Quick Controls 2.
qtquick3d\src\effects is the simplest example I found.
