We are developing a benchmarking framework in C++, with Make and CMake as build tools. The aim of the framework is to allow others who build algorithms to perform head-to-head comparison against prior work. As such, we have integrated a number of state-of-the-art algorithms which users can clone and test within the framework. As many of the algorithms have standard dependencies (e.g Eigen, OpenCV etc), our current solution is to clone all dependencies with specific revisions into a
deps/ directory and ensure that all the different algorithms link against these dependencies.
We are finding that this approach makes it increasingly difficult to maintain something that can easily be built. As more algorithms are integrated into the framework, it becomes virtually impossible to find revisions that will work across all algorithms. Furthermore, it’s unlikely that all users will be interested in building all algorithms currently integrated.
One solution would be to clone each algorithm’s dependencies separately and build each algorithm separately. There are two issues I can find here:
- Some of the common dependencies, such as OpenCV are very large and take lots of time to clone and compile.
- In my experience, having multiple versions of the same library is bound to end with CMake picking the wrong version for some reason, and is often hard to constrain. One often ends up with dependency conflicts across different projects, the system, etc.
- Wherever possible, it’s preferable to make sure that the same version of dependencies is used across algorithms. If one is to perform fair head-to-head comparison, the probability that a difference in performance between algorithm1 and algorithm2 is due to different versions of their dependencies should be minimized.
Attached the tree, perhaps it can give a better idea of the overall structure
