Update CMakeLists to be more configurable

Browse Source 
* Add cxxopts.hpp as a source file to executable
* Add msvc options for compiling
* Add CXXOPTS_BUILD_EXAMPLES option to CMake build
  * This is helpful when using CMake's ExternalProject_add()
  * It is ON by default, but configurable from the command-line.
