FATALDependency proj not found

[ar4development]

I'm trying to build the lib using the following steps:

git clone https://github.com/intel/ad-rss-lib.git
cd ad-rss-lib
git submodule update --init
colcon build

However I'm getting

root@264371cba0f0:/home/ad-rss-lib# colcon build                           
Starting >>> spdlog  
Starting >>> ad_map_opendrive_reader
Starting >>> PROJ4
--- stderr: ad_map_opendrive_reader
FATALDependency proj not found!

Could you advice if I am missing some preconditions.

Thank you!

I managed to build everything only after I have manually built dependencies/PROJ with ./autogen.sh && ./configure && make && make install and then running colcon build..

Thanks for raising the issue. I'm adding an explicit dependency to the colcon.meta's to ensure the correct build order.

colcon build --packages-up-to=PROJ4
followed by
colcon build
should also be a workaround for the issue, but I didn't read the issue before you actually had solved it on your own...
