CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

  call.  Please see the cmake-commands(7) manual for usage documentation of
  both commands.

You may have to fill in some things. I checked that there are many libraries missing in the project, such as json and so on. Take a good look at the error message. 你可能得补齐一些东西 我看了下项目里面缺少不少库哦 比如json什么的。好好看看报错内容。
