ERROR: libvmaf >= 2.0.0 not found using pkg-config

[stderr-to-devnull]

I built (I think) a CUDA enabled libvmaf which I then managed to use in order to build a Linux ffmpeg binary. But my ultimate goal was to build a Windows binary.

On my Windows machine I used media-autobuild_suite before and it built just fine. But now I wanted to try and build it with the (hopefully) CUDA enabled VMAF. So I copied:

• libvmaf.a to media-autobuild_suite/local64/lib/
• libvmaf.so to media-autobuild_suite/local64/lib/
• vmaf.h to media-autobuild_suite/local64/include/libvmaf/
• libvmaf_cuda.h to media-autobuild_suite/local64/include/libvmaf/

...then I fired up the build .bat file and I got the below:

ERROR: libvmaf >= 2.0.0 not found using pkg-config

Important things to note:

1. I encountered the same message ERROR: libvmaf >= 2.0.0 not found using pkg-config when I attempted to cross compile inside my WSL environment
2. In my WSL environment, libvmaf is found just fine when running pkg-config:

   pkg-config --modversion libvmaf
   3.0.0

3. After failing to find a solution, I thought I'd try this autobuild suite but it seems the issue is systemic across environments and it's related to the configure script of ffmpeg

So while I acknowledge that I used non-standard vmaf library files and the issue is with ffmpeg rather than with this suite, I would appreciate some help if possible, in the hopes that it's a rather simple solution which escapes me.
