So far our library structure was that we create libraries which use kendo and those libraries use scss kendo variables. However since we updated to angular 15 and the latest kendo libraries those things don't work anymore.
When we troubleshoot those things we get several errors, first the variable names are completly missing from the file. However even when we remove those and rename the ones which are renamed its still not working saying that inside _variables.scss kendo requires e.g. (look image below) some undefined variable.

This might be a angular problem that angular should allow building libraries even when scss variables are missing, cause inside the root app we will import all scss which is required to make those things build?
OR
There are some new changes in kendo and we arent aware of them. Is there any tutorial on the docs explaining how to build other libraries and use kendo themes e.g. bootstrap to then overwrite default kendo style?
Please if possible provide detailed informations cause we really don't get futher with this.
OR
Maybe now you have split up that theme library into multiple ones and we need to install a new library and import the scss? However we would still like to maybe just use variables and let the root app provide the scss properly.
