Undefined reference to docopt::docopt

[peschkaj]

When attempting to build the example code, I get the following compiler error using both g++ ((Ubuntu 5.4.0-6ubuntu1~16.04.2) 5.4.0 20160609) and clang (3.8.0-2ubuntu4):

CMakeFiles/projector.dir/main.cpp.o: In function `main':

This is on Ubuntu 16.04.1

looks like you're not compiling all the files.
