Build tutorial and configuration is missing

[achirkin]

Hey Michael,

Could you please add a detailed how-to for building the project?
I tried to build it from source without tests, but failed:

-- Could NOT find GTest (missing:  GTEST_LIBRARY GTEST_INCLUDE_DIR GTEST_MAIN_LIBRARY) 
CMake Error at CMakeLists.txt:85 (file):
  file COPY cannot find
  "/home/achirkin/Documents/qua-vis-services/luci-connect/include/easylogging/src/easylogging++.h".


CMake Error at CMakeLists.txt:86 (file):
  file COPY cannot find
  "/home/achirkin/Documents/qua-vis-services/luci-connect/include/json/src/json.hpp".

1. I could not find a way to ask cmake how to build without tests. This line -- Could NOT find GTest... sounds like a fatal error -- I suggest to prepend it with "WARNING ... tests will not be configured".
2. There are some other errors as you see :)
3. Besides cmake issues, I would ask to write down what are the packages needed/optional to build under Ubuntu/Windows with links and an instruction compile (e.g. "cmake . && make" or something like this)
4. qua-vis-services does not refer luci-connect in any way in readme or git .submodules even though building requires it.
