have some questions about the value of precompile prefix header (Yes/No). Here we will explain:(1) If the precompile prefix header is yes, PCH will be pre-compiled, and the pre-compiled PCH file will be cached to speed up compilation. (2) If the precompile prefix header is no, PCH will not be pre-compiled. Instead, it
