      Description

      How to reproduce

      The way RTA reported

      Do a top-level build with qttools.

      cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DBUILD_EXAMPLES=OFF -DOPENSSL_ROOT_DIR=/home/qt/openssl-1.1.1g -DCMAKE_BUILD_TYPE=Release -DFEATURE_system_jpeg=OFF -DFEATURE_system_png=OFF -DFEATURE_system_pcre2=OFF -DFEATURE_system_harfbuzz=OFF -DFEATURE_system_doubleconversion=OFF -DFEATURE_libudev=OFF -DBUILD_TESTING=OFF -DBUILD_SHARED_LIBS=OFF /home/qt/RTA/src-6.1.0 -DCMAKE_INSTALL_PREFIX:PATH=/home/qt/RTA/src-6.1.0/qtbase
      

      Gui applications like designer then cannot run. Error message is

      qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
      This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
      

      This does not happen with per-repo builds.

      Reproduce with qtbase only

      This is apparently not a top-level build only issue as the following way to reproduce proves. Configure and build like this:

      configure -static -nomake tests -- -DQT_BUILD_EXAMPLES=ON -DQT_BUILD_EXAMPLES_BY_DEFAULT=OFF && ninja gui_analogclock && ./examples/gui/analogclock/gui_analogclock
