I cannot figure out how to build this on MinGW32

[LEOcab]

Describe the bug
I can't build the library either as outlined in the front page (using vcpkg) or with CMake as outlined in the wiki.

To Reproduce
Steps to reproduce the behavior:

1. Install MSYS2
2. Open MinGW32 shell
3. Install both the x86 and x64 toolchains
4. Follow the rest of the provided instructions

Expected behavior
THE LIBRARY SHOULD BUILDDDDDDD.

Desktop (please complete the following information):

• OS: Windows 10
• Meson version: n/a
• Ninja version: n/a

Additional context

Output while trying the vcpkg method: (ran from vcpkg directory)
`$ ./vcpkg install jsoncpp --host-triplet=x64-mingw-static --triplet=x86-mingw-dynamic
Computing installation plan...
The following packages will be built and installed:
jsoncpp:x86-mingw-dynamic@1.9.5#2

• vcpkg-cmake:x64-mingw-static@2023-05-04

• vcpkg-cmake-config:x64-mingw-static@2022-02-06#1
  Additional packages (*) will be modified to complete this operation.
  Detecting compiler hash for triplet x64-mingw-static...
  error: while detecting compiler information:
  The log file content at "C:\msys64-crypto\home\user\vcpkg\buildtrees\detect_compiler\stdout-x64-mingw-static.log" is:

  Cannot find port:

  Directory does not exist: C;/msys64-crypto/home/user/vcpkg/scripts/detect_compiler

error: vcpkg was unable to detect the active compiler's information. See above for the CMake failure output.
`

I can't show the output I got with the CMake method provided by the wiki because it's too long, but it seems to be mostly undefined references to items beginning with std::__cxx11::. I'm guessing I have to specify C++11 somewhere but I have no clue how.

Somebody help please? I just want to build this so I can use it on a project but it feels like rocket science. I just need an include folder, a lib folder, and a bin folder with 32-bit MinGW binaries. I don't need any package management
