protobuf cmakelist，msvc utf-8设置

news 2025/7/9 19:43:11

源字符集和执行字符集
源字符集指的是cpp文件中字符串的编码方式
执行字符集指的是exe文件中字符串的编码方式

msvc编译器设置的命令行参数
/source-charset:utf-8 /execution-charset:utf-8

cmake中设置
add_compile_options(“ $<$ <CXX_COMPILER_ID:MSVC>:/source-charset:utf-8>”)

add_compile_options(“ $<$ <CXX_COMPILER_ID:MSVC>:/execution-charset:gbk>”)

# 必须在add_library ， add_executable 前设置，否则无效
add_compile_options("$<$<CXX_COMPILER_ID:MSVC>:/source-charset:utf-8>")# protoc必须要加上这条！！！！！！！！！！！！！！！
