Project imported with QtCreator has missing src files

git clone https://github.com/npisanti/ofxPDSP.git
git clone https://github.com/danomatika/ofxMidi.git
git clone https://github.com/npisanti/ofxSIMDFloats.git

I import ofxPDSP/example-midi_polysynth into QtCreator and click run, but it fails to compile. See error screenshot here.

If I type make Debug on the command line, the program compiles successfully.

I'm on 64bit ArchLinux, OF 0.9.3 from GitHub, QtCreator 3.6.0.

Update: by looking at the .qbs project file, I see two files from src/ are missing:

    files: [
        'src/main.cpp',
        'src/ofApp.cpp',
        'src/ofApp.h',
    ]

The two missing files are voice.cpp and voice.h.

Looking at the import wizard, it looks to me like it always includes the same 3 files found in src/.

At the bottom of this document https://doc.qt.io/qtcreator/creator-project-wizards-json.html it mentions a scanner, which builds a list of files found in a folder, and I don't see it used in the wizard (maybe I missed it).

I don't understand how this scanner works. Here's the source code.

yes the project importer is kind of limited at the moment, it only adds the standard files. i didn't see any option for reading the contents of the folder when i created the wizard. i might have missed it or it might be something they've added afterwards, in any case it would be a great addition to have. if you want to take a look? otherwise i'll try to implement it when i have a moment

I spent a long time trying to figure it out, but the documentation is very limited. In

/usr/share/qtcreator/templates/wizards/projects/vcs/*/wizard.json

they use the Scanner generator, but I have no idea where is the resulting list of files accessible. I thought of using JavaScript to get the list of files placing that into "options", but then I also could not find any documentation about the syntax for those JS calls. For instance I see Util.filename, Util.isDirectory, Vcs.isConfigured but I don't know what that Util or Vcs refers to. Knowing that I could do something like Util.listFiles(...) and include that list inside the generated qbs file.
