[PySide] Pyside configuration error

[Michael Hill]

I'm building FreeCAD using the Flatpak manifest from Flathub, but modified
for Python 3. Pyside2 5.12.1 built successfully using the KDE 5.12
Platform/SDK environment, but the resulting FreeCAD failed with this error:

https://bugreports.qt.io/browse/PYSIDE-1140

(Pyside2 5.12.1 still builds with the 5.12 environment, but now there is a
FreeCAD build error.)

I upgraded to the KDE 5.14 Platform/SDK and modified the source line in the
manifest to point to Pyside2 5.14.1. It looks like this:

  - name: pyside2
    buildsystem: simple
    build-commands:
      - mkdir -p /app/qt5include && cp -R /usr/include/Qt*
/app/qt5include # https://bugreports.qt.io/browse/PYSIDE-787
      - cd sources/shiboken2 && mkdir _build && cd _build &&
        cmake -GNinja
        -DCMAKE_BUILD_TYPE=RelWithDebInfo
        -DCMAKE_INSTALL_PREFIX=/app
        -DUSE_PYTHON_VERSION=3
        -DBUILD_TESTS=OFF .. &&
        ninja install
      - cd sources/pyside2 && mkdir _build && cd _build &&
        cmake -GNinja
        -DCMAKE_BUILD_TYPE=RelWithDebInfo
        -DCMAKE_INSTALL_PREFIX=/app
        -DUSE_PYTHON_VERSION=3
        -DBUILD_TESTS=OFF .. &&
        ninja install
      - cd sources/pyside2-tools && mkdir _build && cd _build &&
        cmake -GNinja
        -DCMAKE_BUILD_TYPE=RelWithDebInfo
        -DCMAKE_INSTALL_PREFIX=/app
        -DBUILD_TESTS=OFF .. &&
        ninja install
    cleanup:
      - /qt5include
      - /bin
    sources:
      - type: archive
        url: https://download.qt.io/official_releases/QtForPython/pyside2/PySide2-5.14.1-src/pyside-setup-opensource-src-5.14.1.tar.xz

      - type: shell
        commands:
          - sed -i 's|\(--include-paths=\)|\1/app/qt5include:|'

Shiboken builds and installs, but the Pyside2 configuration fails like
this:

Running: cd sources/pyside2 && mkdir _build && cd _build && cmake
-GNinja -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/app
-DUSE_PYTHON_VERSION=3 -DBUILD_TESTS=OFF .. && ninja install

CMake Error at CMakeLists.txt:47 (message):
  Could not identify PySide2 version.  Error:

-- Configuring incomplete, errors occurred!
See also "/run/build/pyside2/sources/pyside2/_build/CMakeFiles/CMakeOutput.log".
Error: module pyside2: Child process exited with code 1

pyside_version.py exists and reflects the correct version. Does this
error suggest a different problem?

Note that if I change the Pyside2 source line back to 5.12.1 but still
using the KDE 5.14 environment, Pyside2 builds, and FreeCAD builds and
runs without the
"'Shiboken.ObjectType' object is not iterable" error.

Thanks,

Mike
