Installing libpcl-dev

[Rowan Dempster]

I need to install libpcl-dev from apt to do point cloud processing on VOXL2. However apt would remove voxl-eigen3 to install libpcl-dev, which I'm assuming would break other apps in voxl-sdk (by the way what is the reasoning behind a custom build of voxl-eigen3 and not using apt?).

How would you recommend solving this general problem of modal SDK apps having dependency conflicts with other general use packages like PCL? I'm thinking of building a custom version of PCL that uses the VOXL-SDK compatible version of eigen3, but that might be overkill.

@Rowan-Dempster One solution is to run my new package in a docker container. Not saying this is the best idea, but one possible solution.

@Rowan-Dempster, i looked through the changelog of our project (https://gitlab.com/voxl-public/voxl-sdk/third-party/voxl-eigen3/) and it does not look that there are any changes done to eigen3 itself, i think it is just a package we inherited from VOXL1, which did not use apt.

If you are willing to try it, remove voxl-eigen3 package (which may temporarily break something - note which packages require it). We could potentially update whatever gets broken to be happy with either voxl-eigen3 or eigen3 installed using apt.
