# TODO: Add conditional support for "QtRemoteObjects" via a new "remoteobjects"
# USE flag after an external "dev-qt/qtremoteobjects" package has been created.
# TODO: Add conditional support for apidoc generation via a new "doc" USE flag.
# Note that doing so requires the Qt source tree, sphinx, and graphviz. Once
# ready, pass the ${QT_SRC_DIR} variable to cmake to enable this support.
# TODO: Disable GLES support if the "gles2-only" USE flag is disabled. Note
# that the "PySide2/QtGui/CMakeLists.txt" and
# "PySide2/QtOpenGLFunctions/CMakeLists.txt" files test for GLES support by
# testing whether the "Qt5::Gui" list property defined by
# "/usr/lib64/cmake/Qt5Gui/Qt5GuiConfig.cmake" at "dev-qt/qtgui" installation
# time contains the substring "opengles2". Since cmake does not permit
# properties to be overridden from the command line, these files must instead
# be conditionally patched to avoid these tests. An issue should be filed with
# upstream requesting a CLI-settable variable to control this.
