feat:only generate plugin.qmltypes for release version

[maidamai0]

In debug version, qmlplugindump tool get an error for incompatible Qt version, mix debug and release verison.

Hmm this seems odd to me. qmlplugindump should work even if your qml plugin is a debug build. I will test it later today to make sure that is the case though.

Sorry, I should have pasted the error information:

I'm also surprised by this, but it seems to be true.
There is a similar question in qt forum:qmlplugindump with debug extension.
