How to compile Vdr addon

I want to compile a vdr addon that is not included with LE. This is for wetekplay! I have done the following and was able to compile!

git clone https://github.com/CvH/LibreELEC.tv.git LE-Tvh
cd LE-Tvh
git checkout 9.0/tvh-4.3
PROJECT=WeTek_Play ARCH=arm scripts/create_addon vdr-addon

It compiles fine, but I want add extra vdr plugins but I am not knowledgeable on that! The add I want to add is from here Bitbucket

Thanks

The plugin I am trying to compile is from here

https://forum.libreelec.tv

How would I go about creating a package.mk for this addon? I don't know how to code, can I just use from other add-on and change PKG_URL to that one for channelscan?

thanks

I was able to create a package.mk and it started to compile with

PROJECT=WeTek_Play ARCH=arm scripts/build vdr-plugin-channelscan

It then gives me error cannot find -liconv, any ideas?
