Commit
This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Summary: The method used is rather byzantine. It basically parse the prl files used for Qt internal build system to figure out dependencies as dependencies for cmake files produced by Qt are incorrect. The solution come from https://bugreports.qt.io/browse/QTBUG-38913 and, interestingly, is used within QtWebkit. Test Plan: ninja Check that bitcoin-qt builds.
