Cross colpile lvgl8.3 for arm11 in windows

Dear Engineers,
I want to cross compile lvgl v8.3 as a shared object to use on a device that its CPU is Arm 11 and its OS is a custom linux. I have The needed tool-chain, but I could not find a clear and useful document that explains step by step cross compiling of lvgl. Could any body help me to do this?
Thanks a lot for your support.
