install git https://git-scm.com/downloads/win

install cmake https://cmake.org/download/

pop temrinal and run 'where git' without quotes and note where its at

create conda

in C:\Users\root\anaconda3\envs\NAME_OF_CONDA_VENV_GO_HERE\etc\conda\activate.d

create a file called git_path.bat

@echo off
set "PATH=C:\Program Files\Git\cmd;%PATH%"

if needed replace the path with the actual path gits at

run C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat

change the vs2019_compiler_vars.bat a little

set "PY_VCRUNTIME_REDIST=%PREFIX%\bin\vcruntime140.dll" we want to remove the bin from the path, its not located there.

we are going to change the vars file a LOT. we need to add in the paths of the compilers, the runtimes, everything. below is what got working on  mine with vs 2022.
