Build failed

dfplex is failing to build on lubuntu (Ubuntu 20.04).
cmake v3.18
gcc version 9.3.0

I tried the same environment with the latest dfhack and it didn't have any errors.

you can try commenting that line out. It may not be necessary. (I don't fully understand it.)

I know this is already closed, but just in case it helps anyone: This just happened to me today, and all I had to do was update the websocketpp submodule:

cd plugins/dfplex/server/websocketpp
git checkout master
git pull
