GLPK not detected by cvx_setup

I have GLPK installed as seen here.

yannik@yannik-Inspiron-7580:~$ ls /usr/local/lib
libglpk.a  liblpk.a  python2.7  liblaspack.a       libmdp.a  python3.6

Yet, when I run cvx_setup, GLPK is not detected.

Setting CVX paths...done.
Saving updated path...failed. (see below)

Why is this and how can I fix this?

I’m using Ubuntu 18.04.

I don’t know what’s involved in getting GLPK to work under CVX. However, it appears you have a Mosek capability, and that is superior to GLPK for every problem type.

Have you managed to make it work?

@mcg, Could you share how to enable GLPK?

Nope no luck. Not sure what to do.
