@oniongarlic thx again for your help. downloaded your repo and opened project in Qt Creator.
set kits for android, osx and ios
trying to build I'm getting symbols not found for OSX, some errors building for ios and uncount errors trying to build for android.
at the moment have no idea howto go gon.
howto get rid of the errors and howto include this lib into another app.
do I have to copy all your content into my own app or do I have to build your lib and refer to this from other projects ?
in this case do I need different builds for targeted platforms ?
sorry for these questions - I'm not so familiar with this.
