      Description

      I'm trying to build PySide2 under Flatpak (https://www.flatpak.org).

      I don't know how familiar you are with Flatpak, but reproducing this locally is simple. Create a file "org.pyside.Test.yaml" with the following content:

      app-id: org.pyside.Test
      runtime: org.kde.Platform
      runtime-version: '5.11'
      sdk: org.kde.Sdk
      modules:
        - name: pyside2
          buildsystem: simple
          build-commands:
            - python3 setup.py install --prefix=/app
          sources:
            - type: archive
              url: http://download.qt.io/official_releases/QtForPython/pyside2/PySide2-5.11.1-src/pyside-setup-everywhere-src-5.11.1.tar.xz
              sha256: 9cbc3cbb03c6c1ddba8de7a651c84b269f87ebd4a0991a1f9acc8b2d0ccdfb83
      

      Now from the command line:

      $ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
      $ flatpak install flathub org.kde.Sdk//5.11
      $ flatpak-builder --install build_dir org.pyside.Test.yaml
      

      This results in the following error:

      [...]

      In Flatpak there are two prefixes:
      /usr - read-only shared runtime with all the standard libraries (including Qt)
      /app - application data + bundled libraries
