What is the best way to compile a specific C program that may have
dependencies?

I would like to compile the following C file on an embedded platform:
https://github.com/openwsn-berkeley/openwsn-fw/blob/develop/firmware/openos/bsp/chips/at86rf231/radio.c
However, as you can see, on lines 20-26 of radio.c it references
"radiotimer_capture_cbt":
typedef struct {
radiotimer_capture_cbt startFrame_cb;
radiotimer_capture_cbt endFrame_cb;
radio_state_t state;
} radio_vars_t;
radio_vars_t radio_vars;
So now I need to hunt down where it is defined and make sure I include the
right header.
I have cloned the entire GIT repository here:
https://github.com/openwsn-berkeley/openwsn-fw, and I'm looking for a way
to compile this easily.
Is there a better way to get this compiled other than going through the
brutal dependency nightmare?
My ultimate goal is only to get radio.c compiled and anything it needs. I
do not see any makefiles in this project so I'm expecting they want us to
use an IDE.
