Well.... install make (nvidia's instructions include that).

What's your intended build environment? VisualStudio of msys2/mingw? If 
mingw, did you install the 'c' compiler?

The nvidia instructions don't cover installing a heap of things, like the 
compiler and a lot of packages. (They also say "–-toolchain=msvc" even as 
they're giving instructions for mingw, which is suspect (I haven't looked at 
the code yet to see if it matters.)

So first, make sure you have a working build environment, that's out the 
scope of this list. Then look at the instructions for building ffmpeg-

I use "Option 2: MSYS2" of
https://trac.ffmpeg.org/wiki/CompilationGuide/MinGW

If you're using visual studio, see
https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC

You'll have to manually install any needed packages, usually ./configure 
will tell you when something's missing.

Once you can build ffmpeg without cuda, then try building with cuda. And you 
may want to follow up with nvidia if you're using their instructions.

Later,

z!
