 * `TINYGLTF_USE_CPP14` : Use C++14 feature(requires C++14 compiler). This may give better performance than C++11.
 
+## CMake options

+You can add tinygltf using `add_subdirectory` feature.
+If you add tinygltf to your project using `add_subdirectory`, it would be better to set `TINYGLTF_HEADER_ONLY` on(just add an include path to tinygltf) and `TINYGLTF_INSTALL` off(Which does not install tinygltf files).
