Here is what apt-get installs:

$ sudo apt-get build-dep lyx
[snip]
Les NOUVEAUX paquets suivants seront installés :
   dh-python libboost-dev libboost-filesystem-dev libboost-filesystem1.67-dev
   libboost-iostreams-dev libboost-iostreams1.67-dev libboost-regex-dev
   libboost-regex1.67-dev libboost-signals-dev libboost-signals1.67-dev
   libboost-signals1.67.0 libboost-system1.67-dev libboost-test-dev
   libboost-test1.67-dev libboost-test1.67.0 libboost-timer1.67.0
   libboost1.67-dev libenchant-dev libmagic-dev libmythes-dev libqt5svg5-dev

So the boost libs were missing. I can compile all right now, thanks a lot.
