ebuild claims to be Qt6, yet build system checks for Qt5 deps? How did you stabilise this?

By not running into this issue. Probably because Qt5 was also present.

As far as I can tell, qtrvsim supports Qt5 and Qt6. Or at least tries to at https://github.com/cvut/qtrvsim/blob/853dcc991621125906f3a6817c0bdfb67a388e3e/CMakeLists.txt#L240-L250.

I am  sorry, if I missed something. Your assistance with this is appreciated.

[Comment 11 Andreas Sturmlechner 2024-07-04 11:47:00 UTC]

> find_package(QT NAMES Qt5 Qt6 COMPONENTS Core REQUIRED)
This is essentially automagic for "use whatever we find first". If Qt5Core is present, it would probably first use Qt5 and link with that instead of Qt6, but since in Qt5 the base package is split in many parts, if one like Qt5Widgets is missing, it fails to configure as seen in this bug.

Obviously we can't have automagic in Portage. kid3-3.9.5.ebuild does this to hard-disable Qt6 in the same, very unfortunate, build system mechanism:

>	sed -e "/^ *find_package.*QT NAMES/s/Qt6 //" \
>		-i CMakeLists.txt || die # ensure Qt5 build

You could adapt it to your needs to de-select either-or.
