Odd jansson problem

[ab1jx]

I'm trying to build from your master.zip on a Raspberry Pi ZeroW under current Raspbian. I had libjansson and libjansson-dev from the Raspbian debs installed, then when I got this error I tried the jansson install mentioned in doc/windows-build.txt, but I still get the same problem. I have built other miners that used jansson, but not on this machine. I have a cgminer running on another Zero without doing anything special.

There's nothing in the submodules/jansson dir, except I built Jansson from sources there. Locate shows:

Not that this is really an issue with the program, just something odd about trying to build it. The OpenCL I'm hoping to use when I get that far is at https://github.com/doe300/VC4CL
