Hate to admit, was in a hurry so I just nuked the system library copy,  
and replaced it with the ones that pybombs compiled. That worked, but  
not anywhere near as cleanly as the solution you’ve outlined… :-/

Did not work the way I expected either, had to uninstall the system  
variant before cmake found that it could actually use the variant I put  
first.  
I reran from cmake, but it resolved to the system header files and lib,  
and I don’t understand why.  
The recipe is included below, while the cmake file is here:
