How do I set a path in Visual Studio?
Search MSDN for “How to: Set Environment Variables for Projects”. (It’s Project>Properties>Configuration Properties>Debugging “Environment” and “Merge Environment” properties for those who are in a rush.) The syntax is NAME=VALUE and macros can be used (for example, $(OutDir)). For example, to prepend C:\Windows\Temp to the PATH: PATH=C:\WINDOWS\Temp;%PATH% Similarly, to append $(TargetDir)\DLLS to the PATH: PATH=%PATH%;$(TargetDir)\DLLS
