### Compilation Reference
The [README.md](https://github.com/google/double-conversion/blob/master/README.md) file in the code repository details the procedures for compiling the double-conversion library using CMake as well as the testing methods. This document focuses on the building, compilation, and testing of the library. If you have any questions during library porting, refer to the **README.md** file. For porting of other third-party libraries that can be independently built with CMake, you can refer to the compilation guides provided by the libraries.
