  -save-temps=<arg>        Do not delete intermediate files.
  -no-canonical-prefixes   Do not canonicalize paths when building relative
                           prefixes to other gcc components.
  -pipe                    Use pipes rather than intermediate files.
  -time                    Time the execution of each subprocess.
  -specs=<file>            Override built-in specs with the contents of <file>.
  -std=<standard>          Assume that the input sources are for <standard>.
  --sysroot=<directory>    Use <directory> as the root directory for headers
                           and libraries.
  -B <directory>           Add <directory> to the compiler's search paths.
  -v                       Display the programs invoked by the compiler.
  -###                     Like -v but options quoted and commands not executed.
  -E                       Preprocess only; do not compile, assemble or link.
  -S                       Compile only; do not assemble or link.
  -c                       Compile and assemble, but do not link.

  -shared                  Create a shared library.
  -x <language>            Specify the language of the following input files.
                           Permissible languages include: c c++ assembler none
                           'none' means revert to the default behavior of
                           guessing the language based on the file's extension.

Options starting with -g, -f, -m, -O, -W, or --param are automatically
 passed on to the various sub-processes invoked by g++.  In order to pass
 other options on to these processes the -W<letter> options must be used.

make -j{cpu-n}

CMake官方版是一款构建、测试和打包软件的跨平台编程工具。CMake官方版是用于控制软件使用简单的平台和编译器编译过程独立配置文件。CMake生成本机makefile和工作区，可以使用用户所选择的编译器环境。

cmake .. ${options}
make -j{ncpu}
make install

github:有在实际构建中依赖网络，有可能因为网络原因或者库的消失导致构建失败，通常不提倡使用github。
gitlab:本地库管理，不过要注意库版本的管理。
# github,gitlab 通常要搭配的 git submodule 来使用，在做版本管理的时候要注意更新以及submit。
conan:包管理工具
localfile:将源码到本地，通常万无一失唯一可能导致源码包过大。
