Hi, there.
I build the vtk source on branch master with Qt5.15.2 on ubuntu2004.
when I run the test app, it failed like below information.
> > anyone know how can I make the test run successful? very thanks.

You may need to set the `QML2_IMPORT_PATH` environment variable to be able to load them (I don’t know where Qt searches by default). FWIW, CTest will set this, but you’ll need to set it manually if you’re going to run the executable by hand.

very thanks. It works.
I export it then test run a part. below is the log:

That test expects to be told where its baseline images and input data exist. You can see how it gets run through CTest [here](https://open.cdash.org/test/461236349) (click the `Show Command Line` “link”). It may just be easier to run `ctest -R TestQQuickVTKRenderItem` instead of trying to run it by hand.

@ben.boeckel Very tks. what you tell me is very useful, more than solve the problem.
