D7094: Include a module for finding qml imports as runtime dependencies

[Harald Sitter]

sitter added a comment.


  qmlplugindump not being found needs to be handled somehow. Other than that only minor nitpicks.
  
  (as always I'd also be more confident if it had a test case ;))

Not sure if we have a common practice for this, but I am thinking this needs to have a `find_program()` and give suitable output if qmlplugindump itself cannot be found. Pointing the user towards qtdeclarative being needed to check qml dependencies.

If I read the code correctly it takes vargs equal to `find_package`, may be worth mentioning.

Description should probably mention that this is a qml module.

"QML module ${MODULE_NAME} is a runtime dependency" or something like that.
