Hi Chenbinhao0352,
Do you mean that the $(VCTarget) is $(VCTargetsPath)? The macro seems to be stored in the configuration file of msbuild tool. At last, I find it in MSBuild.exe.config file.
Based on different properties and application environment, different macros are stored in different configuration files. So if you want to find other macros, maybe you need to take much time on it.
Best Regards,
Dylan
