how can I specify the additional include dir BigProject/IncludeDir? For Windows build I use $(SolutionDir)..\include setting. VisualGDB sends the Windows path to the remote machine and I do not see a RemoteMachineSolutionDir or something like that macro. Thank you.
For most of the cases we would advise simply using relative paths (e.g. ../SolutionDir). The relative paths are always interpreted relatively to the project directory.
