build help needed.

[AAH134]

thanks for a wonderful repo,

I was trying to build on ubuntu 20.04
but I dont mind which one is used.

I did installed all things needed in switch2OSM however I am having an issue,

the error message as follow:

CMake Error in src/CMakeLists.txt:
Found relative path while evaluating include directories of "tilesweep":

"MAPNIK_INCLUDE_DIR-NOTFOUND"

---

I tried to install mapnik from src code but no luck,

would anyone mind point me to any help to build the source,

I was able to build it on Ubuntu 20.04 after installing libmapnik-dev using apt.
