      Setup used to build:

      Heading 1 Heading 2
      OS Fedora 35
      GCC 11.2.1
      commit ID 78c9de58c0eaa559220484a1f8822bc1c53b0a99
      configure command line developer-build -skip qtwebengine -skip qt3d -prefix /mnt/linux/Qt/5.15.8/gcc_64-developer_build

       

      As a side note, adding

      -c++std c++14

      to the configure command line did not help. Seems like it doesn't get passed down to this Makefile.
