EDK2 編譯時期前置作業概略

我們在 build UEFI Application 時，第一個步驟便是會呼叫 edksetup.bat，以下是針對我感興趣的部份作記錄。

1. Call edksetup.bat, it will call BaseTools\toolsetup.bat.
2. In BaseTools\toolsetup.bat, if it can't find Conf\target.txt and Conf\tools_def.txt, it will copy BaseTools\Conf\target.template and BaseTools\Conf\tools_def.template to Conf folder to generate Conf\target.txt and Conf\tools_def.txt.
3. When you call build.exe(BaseTools\Source\Python\build\build.py), it will pass these two files in LoadConfiguration function.
