How to generate CMakeLists.txt.user with bash script

Wi have a rather large projet that takes time to configure manually, so we decided to make a bash scrip to do everything for us.

we're on Ubuntu 16.04 We're using c++ and CMake in our project We're using QtCreator to work on the project

The bash script is allmost done, but I am having trouble configuring QtCreator settings: I did manage to modify the kits directly in .config/QtProject/qtcreator/profiles.xml

But i can't find how to create the QtCreator's CMakeLists.txt.user file with a bash script

does anyone know how to create a CMakeLists.txt.user file with a bash script if it's possible?
