This patch integrates the code generation module into the build system. All depenendcies are tracked through CMake targets. Modifying the cost functor will automatically trigger code re-generation. All this functionality is defined in the CMake function ceres_generate_cost_function_implementation_for_functor in CeresCodeGeneration.cmake. A hello world usage example is included in examples/CMakeLists.txt. Change-Id: I23b8b6698d1ea51cf3d788a47afcf39f8c5ce327
