	I added Include Directories to the project (Configuration Properties > VC++ Directories...). However, I still get “No such file or directory” error. There is no such a problem when I do the same in ordinary C++ Console App project.

	Hi, the Visual Studio project properties are only used for intellisense and considered read-only for Arduino. Are you trying to add paths that allow header files to be referenced or add paths that allow additional .cpp/.c files to be compiled.

I am trying to add paths that allow header files to be referenced. To compile additional .cpp I add them to the current project.

	Great. Currently you have to add the includes as -I properties in extraFlags via the F4 project properties -I"some path" -I"some path2"; If you follow the guide in yellow above you will see all the build variables such as, if I recall, "project_path" You can use {build variables} to make relative paths if required. -I"{project_path}/../../somepath" -I"some path2";
