I used default values except for the install paths. According to the
docs "The Makefile/solution builds a static encoder.lib library and a
standalone x265 executable". Although I found the standalone used a
dynamic library that is also created so you get both the .a and .so.

Static ffmpeg compile is by design.

Ahh so for static the libs move from Libs.private to Libs?

I will have a play with this, and the the suggestions regarding '
- --pkg-config-flags="--static" '  from the thread Clément suggested.
