Here is a complete build recipe direct from Wurstgelee for building trianglesd. Wurstgelee included details for working with iquidus block explorer. After downgrading SSL for compile, you can install SSL 1.1.1 using sudo apt-get install libssl-dev.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libqt4-designer libqt4-opengl libqt4-svg libqtgui4 libqtcore4 libqtwebkit4 qt4-dev-tools libqt4-dev gcc-4.9
sudo apt-get install build-essential libssl-dev libdb-dev libdb++-dev libqrencode-dev libevent-dev libminiupnpc-dev libboost-dev liblevedb-dev libboost-all-dev
### fix gcc version see also:
https://t.co/Gf8iyTP82Esudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 10 \
--slave /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-4.9 \
--slave /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-4.9 \

sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 10
### downgrade sslsee also:
https://t.co/yr97vIF3mCsudo apt remove libssl-dev
cd /opt/build
wget
https://t.co/bmimHJkfVs dpkg -i ./libssl-dev_1.0.2g-1ubuntu4.19_amd64.deb
### trianglesd code to work with iquidus:Remove line from src/rpcrawtransaction.cpp :entry.push_back(Pair("time", (int64_t)pindex->nTime));
and recompile it. you will find this line between 90 to 100 number of line it's a easy and fast solutions
### build trianglesdsudo apt-get install git
