request for a minimal Readme / error during initial build

[robinmoussu]

Hello, I was going to try to use this project ton make some remapping on my x-bows, but I didn't really understood where to start. Is it possible to add a minimal Readme.md that contains a list of command to copy-paste. I was expecting to do something like git clone && git submodule init && git submodule update, then mkdir build && cd build && cmake .. and finally ./xbows --help then probably ./xbows ../share/default-prog1.yaml.

Unfortunately when doing cmake .., I got the following error:

CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

It isn't directly compilable - if you refer to #1, you see the modified CMakeLists.txt I use.

As well as some additional patches.

Hi @robinmoussu I'll work on getting that simple scenario to work. Obviously I haven't tried it from scratch yet :-(

@robinmoussu @peterhoeg The basic clean compile sequence should work now. Please give it try.

I added doc/quick-start.md. Please let me know if that works for you. It's not pretty but it works for me.
