Setup.py build fails with fatal error C1083: Cannot open include file: 'stddef.h': No such file or directory

[NaNraptor]

Note: To get to this error I first resolved the CL.exe and LIB.exe not being on my PATH. Also I am runnning Win10

What it says above basically. This is strange since stddef.h resides in C:\Program Files (x86)\Windows Kits\10\include\10.0.19041.0\ucrt but that exists and is included using the -I flag so I am not sure what is going wrong (also I verified the stddef.h file does in fact exist in that dir).

Here is a list of the python packages installed in my venv:

Package     Version
----------- --------
cffi        1.15.0
glfw        2.5.1
numpy       1.22.3
pip         22.0.4
pycodestyle 2.8.0
pycparser   2.21
setuptools  58.1.0
vulkan      1.1.99.1
wheel       0.37.1
