* Add mingw-w64-cmake-static as a separate package
* Fix linker errors (FREETYPE_DEPENDENCIES really must include `-lfreetype`
itself due to the cyclic dependency between FreeType2 and Harfbuzz
* Add patch to fix static compilation of qt6-tools
* Add certain variables to find Qt's dependencies to the CMake
toolchain file because these variables would otherwise needed to
be set every time Qt 6 is used
* Add a static variant
* Not fully tested yet
* Further repos besides base and svg will be added later
