This will introduce RAPIDJSON_BUILD_THIRDPARTY_GTEST option. If it is set to TRUE, cmake will look for GTest installation in `thirdparty/gtest` before looking in other places. Current default value (OFF) for RAPIDJSON_BUILD_THIRDPARTY_GTEST represents previous behaviour when system-wide gtest installation is used whenever possible. This commit will as well eliminate problem described in #309 when source directory found is `thirdparty/gtest` while include files are found system-wide. This however won't give the user possibility to select gtest installation to use.
