"Qt comes with Dual Licensing, which includes both commercial and open source options. To build a proprietary mobile application, you need the Commercial Qt license, within which Qt for Application Development is sufficient for pure mobile and desktop app development."
KDE already has a meta-build tool for C++ called Craft, which handles dependency management and cross - compilation for CMake-built applications and libraries.
AFAIK, Craft is only the most popular tool to build KDE software on (or perhaps for) Windows. On Linux, it's kdesrc-build (OG, Perl) or kde-builder (more recent, Python).
