Build error, proj-includes. proj_api

[iangarnerh]

Hi,

I am installing VENTOS on Ubuntu 20.04 and I am encountering a problem during the execution of the runme script, once it starts installing SUMO. It checks for many dependencies but it fails to find proj_api.h and it throws an error. Here are the last lines of the output which show the error.

checking for main in -lproj... yes
checking proj_api.h usability... no
checking proj_api.h presence... no
checking for proj_api.h... no
configure: error: proj-includes not found in "/usr/include".
make: *** No targets specified and no makefile found. Stop.

I should note that the file proj_api.h does exist in the /usr/include directory.

Thanks.
