Problem with static deployment

[Magnus21]

Hey, I have a problem with the static deployment of my application.
The project is this one: https://github.com/Magnus2552/quickcurver/
When I try to run qmake -config release, it just says Project ERROR: Plugin material is missing a classname entry, please add one to the qmldir file.. It compiles fine, when I don't try to build a static version, so I don't know what is going wrong.
The source of the problem is for sure the qml-material plugin that I use: I import the qml-material plugin the way that it is described here in this section, is there anything else that I have to do for a static compilation?
Thanks in advance
Steps to reproduce my problem:

1. Clone my repo including submodules (Installation instructions)
2. Run the following command sequence

cd quickcurver
mkdir build
PATH=/path/to/qt/bin:$PATH
export PATH
qmake --config release ..

I solved this finally by linking to the plugin as well on compilation.
