How to set path to qmake *.pro file in downloaded zip from github.com?!?

snapcraft

Hi
I strugle to create my first snap file. I notice some progress, but suprisingly I am stuck with compilation QtCsv library. I think the problem is with zip file that contains sub dir called qtcsv-1.4.1 snapcraft is not wise to check content of this sub dir after unpacking. So it reports error. My snapcraft.yaml is as follow, given error is bellow:

name: backup
version: '0.1'
summary: Simple backup daemon

    Simple backup daemon.

grade: devel # must be 'stable' to release into candidate/stable channels
confinement: devmode # use 'strict' once you have the right plugs and slots

apps:
    backup:
        command: bin/backup

parts:
    7z:
        plugin: nil

    qtcsv:

        plugin: qmake
        source: Backup/

“parts..source-subdir string A path within the source to set as the working directory when building”

    qtcsv:
        plugin: qmake
        source: https://github.com/iamantony/qtcsv/archive/v1.4.1.zip
        source-subdir: qtcsv-1.4.1

Should fix it.
