1. I am trying to install GROMACS 2020.1 on my windows 11 OS, after downloading and extracting the gromacs 2020.1 tar file, it does not have an api folder (however has one api folder in the src folder of the tar file) and misses three files - flake8, black.toml, and CITATIONS.cff. Can someone please tell if the api in src folder is the same one that needs to be the tar file or is it a different one? Can I relocate it to the gromacs tar file?

How can I get access to the api folder, why is it not present in the tar file itself?

2. To create the build folder, I am using the command line: cmake -G"NMake Makefiles" -S. -B./build -DGMX_GPU=off -DGMX_FFT_LIBRARY=fftw3 -DCMAKE_BUILD=Release -DBUILD_SHARED_LIBS=off -DFFTWF_INCLUDE_DIR="C:\fftw-3.3.5-dll64" -DFFTWF_LIBRARY=";C:\fftw-3.3.5-dll64\libfftw3f-3.lib"

However, I’m unable to create the build folder and find errors while configuring.

3. Also please tell me how I can compile the NVIDIA GPU with GROMACS for better

performance?
