OLED Tools Package Build Error

Hello everyone,

I'm now trying to build the an openwrt package from this github repo:

It is a packege to drive an OLED display, I followed the instruction on github but when I execute the: make package/oledtools/compile V=sc the following error is generated:

make[1]: Entering directory '/home/jokerx86/openwrt'
make[1]: *** No rule to make target 'package/oledtools/compile'.  Stop.
make[1]: Leaving directory '/home/jokerx86/openwrt'
make: *** [/home/jokerx86/openwrt/include/toplevel.mk:230: package/oledtools/compile] Error 2

I also tried to build the helloworld example on the wiki and everything worked just fine.
Any help will be very appreciated I do not know why this error comes up !
