Boost_system_mt link error

Just tried to build zcashd but got this unresolved link error:

OS: Fedora 26
g++: g++ (GCC) 7.1.1 20170622 (Red Hat 7.1.1-3)
Boost version: 1.61.0

Shouldnt the regular boost_system library be enough ??
I do have all the boost libraries built and available.

Do i have to rebuild the boost libs with mt support ?
or is there anyway to specify not to look for the _mt version of this library?


btw: i did see the other topics with this same error, but not sure if i saw a solution.
