Subject: [PATCH] qtcore: Fix cmake macro compat. for upgrade from <Qt-5.14
In upstream commit:
https://code.qt.io/cgit/qt/qtbase.git/commit/?h=5.14&id=63d9cd17
_populate_$${CMAKE_MODULE_NAME}_plugin_properties in 5.14.0 gained an additional argument
IsDebugAndRelease without providing backward compatibility. This macro is used (at least) for
QtGui and QtDesigner plugins added by qtimageformats, qtsvg, qtvirtualkeyboard and qtwayland.
During upgrade from <Qt-5.14 to >=Qt-5.14, as a consequence of slot upgrade rebuilds, some
reverse dependencies are slated for rebuild before these Qt consumers have been rebuilt and their
cmake files regenerated, leading to cmake errors like:
https://bugs.gentoo.org/703306
https://bugs.gentoo.org/705198
From mkspecs/features/create_cmake.prf:
# CMAKE_DEBUG_AND_RELEASE is used to tell the _populate_$${CMAKE_MODULE_NAME}_target_properties
# functions whether a Configuration specific generator expression needs to be added to the values
# of INTERFACE_LINK_LIBRARIES and INTERFACE_LINK_OPTIONS. For debug_and_release builds, we do need
# configuration specific values. For singular builds (only release or only debug), we want the
# values to be applied regardless of the configuration.
# This would allow on Linux and macOS (and with a recent enough version of CMake on Windows) to
# build a Debug configuration of an application, even if Qt was built in a Release configuration.
qt5-build.eclass is configuring either as 'release' or as 'debug', so we make IsDebugAndRelease
optional and default to FALSE.
