How can i build this library in VS 2017?

[dota17]

• Describe what you want to achieve.
  I know i can use single_include in my project, but i want to build and test this library in VS 2017, especially i add my code.

• Describe what you tried.
  In VS 2017, i open this library as CMake Project with File - Open - CMake....
  And then, CMake - Build All.

But i got these error:

Also, these error is similar to #664 (comment)

• Describe which system (OS, compiler) you are using.
  Windows 10

• Describe which version of the library you are using (release version, develop branch).
  -- Building for: Visual Studio 15 2017
  -- Selecting Windows SDK version 10.0.17763.0 to target Windows 10.0.18362.
  -- The CXX compiler identification is MSVC 19.16.27035.0

[nlohmann]

We build with MSVC 2017 in the CI, see https://ci.appveyor.com/project/nlohmann/json/builds/30517983. So there should not be any problem.

Solve. If anyone has same issue, please ensure

1. install mingw
2. download ninja from https://github.com/ninja-build/ninja/releases/download/v1.6.0/ninja-win.zip
3. follow the scripts of appveyor.yml

finally, you can get nlohmann_json_sln.
Open it, modify code and then rebuild in VS 2017.
