Can't seem to find the correct dependencies to make this library

[canyon289]

Hi,
I'm trying to make this but am getting the error below. Tried for a while to find the right packages to install after using the one in the README but am coming up short. If possible any help or pointers would be appreciated.

Thanks for developing this library

hmmmm ... I'm neither good in coding nor X11 servers and such stuff, but

'fatal error: X11/Xatom.h: No such file or directory' sounds like a qualified message,

found that file on a fresh ubuntu install, which is somewhat pimped for compiling, in
/usr/include/X11, from here on a good search engine or google may help to get
on the board.
