Errors building proj 6.0.0 or later

[mludlum]

This repo was a huge help because we needed vertical datum calculations from the proj library in our Android app.

I am having trouble building proj after version 5.2.0. The build scripts of those versions use sqlite3 to build proj.db. I modified proj.Dockerfile with the following in bold (after successive errors with pkg-config, then sqlite3 binaries, etc.), but it still can't find sqlite3.h even though it should be placed in /usr/include based on my manual tests in a working docker image for 5.2.0. Is there a way to append the include path in the docker build?

Changes to proj.Dockerfile

RUN apt-get update && apt-get -y install
wget \
pkg-config \
sqlite3 \
libsqlite3-0 \
libsqlite3-dev

I also tried adding this line to the Dockerfile but that caused a bunch of other errors:

ENV CPATH $CPATH:/usr/include

Here is a working dockerfile for building PROJ7.0.0:

You will need to have built SQLite3 for android. I did this using BAD and the latest SQLite (3.40.0).

This won't work for builds past PROJ8.2, as they switched entirely to cmake. I'm still trying to get PROJ9.1.1 to build...
