It compiled more or less out of the box. The changes I made were mostly
to link with additional libraries for functionality that on Alpine have
been put into those libraries. I made these changes by modifying the
output of cmake, which is the reason for my mail to this list: I want to
to find out which files to modify so that cmake produces the right
output for Alpine. Then I'll create a branch/PR.

That's what I'll find out.  As written in my post said Cog VM
successfully runs a minimal Pharo image doing FFI and Fuel. 

I'll be testing it with the regular image running some kind of webapp.

I've also put the Docker image on Dockerhub, but I just looked again and
see that it is missing libgit2, libssh2, etc., so probably no good for
running the regular Pharo image for now.
