#FIXME: Restore Python 2.7 support after this upstream issue is resolved:
#    https://bugreports.qt.io/browse/PYSIDE-508
#Even after this issue is resolved, further ebuild changes will probably be
#needed to fully support Python 2.7. Unlike PySide2 and Shiboken2, the root
#"CMakeLists.txt" file in pyside2-tools provides no ${PYTHON_EXECUTABLE} option.
#Instead, the ${PYTHON_EXTENSION_SUFFIX} and ${PYTHON_BASENAME} options must be
#passed with values specific to Python 2.7. Additionally, note that the
#"python2.7-config" command provides no "--extension-suffix" option.
