 1. Compile Enviroment
 ==========================================
     My build envrioment is CentOS 7.8 x86_64. So here I first explain how to create the build environment from scratch.
-    Because Ventoy is based on many open source projects, so the envrioment is important. I suggest you test it on a virtual machine first.
