Configuring a single-config qtopcua might fail to build tools when built against a multi-config Qt

Configuring and building qtbase with

qtbase/configure -debug-and-release -force-debug-info -prefix $PWD/../installed
ninja install

And then trying to build qtopcua with

$qt/bin/qt-configure-module ../../../worktrees/dev/qtopcua -- -GNinja -DCMAKE_BUILD_TYPE=Release
ninja

will skip building all qtopcua tools, one of which is qopcuaxmldatatypes2cpp.

This happens because of code in

https://github.com/qt/qtbase/blob/1da7558bfd7626bcc40a214a90ae5027f32f6c7f/cmake/QtToolHelpers.cmake#L173

EXCLUDE_FROM_ALL skips any config that is not RelWithDebInfo, which is not the configured Release.

The code should build all tools, when it detects that a single-config generator is used to build a repo that is built against a debug-and-release qtbase.
