How to include just one library from local disk?!?

snapcraft

Hi
As I wrote I strugle to create my first Snap package. I do great progress and I am near success, but I need help. When I create my snap i got message:
Files from the build host were migrated into the snap to satisfy dependencies that would otherwise not be met. This feature will be removed in a future release. If these libraries are needed in the final snap, ensure that the following are either satisfied by a stage-packages entry or through a part:
home/szyk/Qt/5.9.6/gcc_64/lib/libQt5Core.so.5
home/szyk/Qt/5.9.6/gcc_64/lib/libicudata.so.56
home/szyk/Qt/5.9.6/gcc_64/lib/libicui18n.so.56
home/szyk/Qt/5.9.6/gcc_64/lib/libicuuc.so.56
So I think I should fix it some how. But I ame failed with this. Mainly because ther is no turorial for such case, and current snap documentation is entirely broken (eg.: https://docs.snapcraft.io/snapcraft-yaml-reference/4276 filesets reference is empty!).
So I think I should create parts: qt: plugin: dump, source: /home/szyk/Qt/5.9.6/gcc_64/lib but how to specify library (or libraries) to include?!?
My snap is like this:
name: backup
version: ‘0.1’
summary: Simple backup daemon
description: |
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
        stage-packages:
            - p7zip

    qtcsv:
        plugin: qmake
        source: https://github.com/iamantony/qtcsv.git
        source-tag: v1.4.1
        
    common:
        plugin: qmake
        source: Libs/Common
        
    backup:
        plugin: qmake
        source: Backup/

    qt:
        plugin: dump
        source: /home/szyk/Qt/5.9.6/gcc_64/lib
        filesets:
            - libQt5Core.so

And error I got is like this:
Issues while validating snapcraft.yaml: The 'parts/qt/filesets' property does not match the required schema: ['libQt5Core.so'] is not of type 'object'

Ok! I nothing found on the net (after using google, bitg and duckduckgo), but I recal somewhtre i see filesets: include: and exclude: So I type include: and got another warning. My snapcraft.yaml is like this:

name: backup
version: '0.1'

The execstacks are going to be cleared for the following files:
- /home/szyk/!-pro/Backup/prime/libQt5WebEngineCore.so.5.9.6
To disable this behavior set `build-attributes: [keep-execstack]` for the part.

And I think most of this is unwanted as I simply use only libQt5Core.so (without graphics nor audio)… How to fix this?!?

And finally I got following error:
FileNotFoundError: [Errno 2] No such file or directory: '/home/szyk/!-pro/Backup/prime/bin/backup'
I am not sure why this happen. I set DESTDIR=$$ROOT_PROJECT/…/Backup-work in /home/szyk/!-pro/Backup/Backup/Backup.pro . But I think plugin should be wise enough to handle this…
