"c1: fatal error C1083: Cannot open source file: 'c/triangle.c': No such file or directory" error while building from source

I am getting this error while trying to build triangle from source:

I am using Windows 11, anaconda 3, python 3.9.17 I tried installing different versions of microsoft build tools but I get the same error every time. I even tried on a different machine with different version of anaconda and python, but still im getting the same error. Can somebody help me in fixing this issue?

I believe you need to download the c source files, they are located in another repo. The files in this repo are just a python wrapper to that c library.

In a conda environment maybe it's easier to simply do conda install -c conda-forge triangle

You may have to use the --recurse-submodules option when cloning the repository. The C source files are located in a separate sub-module. They had to be put in a separate repository because their author uses a different license than the wrapper code.
