I have successfully compiled a few small C programs using the default includes for C projects in Eclipse. These include:

C:\Program Files\Microsoft SDKs\Windows\v7.1\Include
C:\Program Files\Microsoft SDKs\Windows\v7.1\Include\gl
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\Include

I have now edited the INCLUDE environment variable (Properties -> C/C++ Build -> Environment) to also contain:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.2\include

Any attempts to include header files located in this last directory are marked as 'unresolved inclusions'. The Includes 'folder' in my project does not change, either. The initial includes (Microsoft SDK) remain fully functional. Have I missed something while trying to add additional include paths? I've triple-checked the spelling and location.

NOTE: When including the full directory to a header file (#include "C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.2\include\cuda.h"), things work just fine. I'd really rather avoid doing that, though.

The INCLUDE environment variable is not parsed by Eclipse. You must add the include paths in Project Properties->General C/C++->Paths and Symbols: Includes

Thank you for that clarification. Is there any purpose to setting the environment variables then?

The Visual Studio compiler parses the environment variable.
