# Usage: Make script executable and run it. It builds and installs the packages.
#	$ chmod +x ./build.sh
#	$ ./build.sh

PROJ_VER='7.2.1'

# PROJ 8 provided by Ubuntu can't be used. We build version 7, and install in /usr/local/
function install_proj_7(){

	apt-get -y install cmake sqlite3 libsqlite3-dev libtiff-dev libcurl4-openssl-dev

	wget -P/tmp/ https://github.com/OSGeo/PROJ/releases/download/${PROJ_VER}/proj-${PROJ_VER}.tar.gz

I had the same problem. this snippet almost worked for me:

line 59

< 		dh_shlibdeps --dpkg-shlibdeps-params=--ignore-missing-info
>		dh_shlibdeps --dpkg-shlibdeps-params="--ignore-missing-info -l/usr/local/lib"

Python bindings still produce segfault upon exit but seem to work anyhow.
