I am trying to use GO with SFML and in a sample program.
I need to install package gosfml using "go get".  

I am on Mac OSX.

I have SFML compiled and installed SFML from source.
The include files are under /usr/local/include/SFML 

The following command gives the error of a header file not being found.

```
> go get github.com/manyminds/gosfml

# github.com/manyminds/gosfml
go-proj/src/github.com/manyminds/gosfml/circleShape.go:7:11: fatal error: 'SFML/Graphics/CircleShape.h' file not found
 #include <SFML/Graphics/CircleShape.h>
          ^
1 error generated.

```

How can I configure GO to find the header file?

Thanks (new to Go)
