VG `make deps` fails to compile vcflib on mac
I'm having trouble compiling vg on macOS Catalina 10.15.6.
I followed the build instructions in the README and even looked at the Travis config for macOS but couldn't figure it out.
Looks to me like the linker can't find vcflib, here's the error
The problem seems to come from this section of the Makefile
What could I be doing wrong?
