I am trying to get MLPack to work in Eclipse, but have some problems with including a header file. 

I manage to read a header file in Eclipse 

```
#include <neighbor_search.hpp>

```

This header file calls itself 
 `#include <mlpack/core.hpp>`.
I included in Eclipse in the library path the path just upto mlpack/core.hpp, i.e. 
/usr/include/MLPack/mlpack-1.0.8/src in the includes tab of paths and symbols. 

I get the error message though:
 /usr/include/MLPack/mlpack-1.0.8/src/mlpack/methods/neighbor\_search/neighbor\_search.hpp:26:27: fatal error: mlpack/core.hpp: No such file or directory

```
 #include <mlpack/core.hpp>

```

How do set my path correctly so that `<mlpack/core.hpp>` will be found?
