This is correct, but not enough. The fix of the qhelpgenerator detection works only when the cmake config module for it is installed, which is shipped in qttools5-dev. Sadly, this package is not installed by all the Frameworks packages that generate QCH documentation, so uploading extra-cmake-modules with the above commit will do not it alone. The additional fix is to add also qttools5-dev as build dependency, and possibly also limit the documentation building to indep-only builds (since the QCH files are shipped in arch:any -doc packages). Imagine that there are almost 80 sources of Frameworks, and 60 of them provide a QCH documentation... -- Pino Toscano
