you must add include directory to the project.
You need to set up the project properties with the correct paths etc.
In the samples you should find a template project. If not, go through the project properties for a project that works and copy them to your new project.
When I got through properties of a working project I didn't noticed anything special.
Could someone specify where and what properties I should change
These are the common things, not sure what environment you are using:
Additional Include Directories, option /I
Additional Library Directories, option /LIBPATH
