Does qmake have the similar setting? a qrc file would be able to be applied in both qmake and cmake files, right?

qmake does miss the high level abstraction for QML modules. But if you're asking whether you can embed qml files without a .qrc file ... you can:

assets.files = file1.qml file2.qml
assets.prefix = /

RESOURCES += assets

Or you guys are dropping qmake?

Not any time soon :) But we don't develop it much further.

But what about security? If there are using of qt_add_qml_module() will be it stored in application in plain QML text or it will be transformed in C++? Haven't found any info about it in any manuals? Main reason of using *.qrc within QML were security. It was making harder process of reading QMLs.

qt_add_qml_module() allows to use the Qt Quick Compiler , which actually generates C++ code: https://www.qt.io/blog/the-new-qtquick-compiler-technology . If it can't be used, it falls back to qrc though.

(But please note that embedding QML sources in the binary via qrc is obfuscation as best. It's not rocket science to extract the sources back if you have access to the binary).

For the 'cluttering' aspect, you can use include() and CMake variables to separate things if you want to. But personally, I think the list of files is the core of a build system, so I think 'hiding' it in a separate .qrc file is actually a bit of a misfeature ;)
