Ahhh, interesting approach.

When reading the following please consider that all I'm writing is not based on technical understanding of fis-gtm but I'm rather expressing a gut feeling based of past experience with other programs. It might be wrong and should be considered with a grain of salt. I have the strong feeling that fis-gtm could profit from some kind of modern build system, so in principle I think what you are trying to do is a good move for upstream fis-gtm. My prejudice that you should know cmake tricks well enough from your work at kitware makes cmake a straightforeward choice for you and the step sounds logical. However, if I were in your shoes I would try to make pretty sure that other fis-gtm upstream are really happy about this step. If this is the case I would really applause your plan because it not only would make fis-gtm easier to package from a Debian point of view but it also might simplify integration into other distributions and will make fis-gtm probably more widely accepted. On the other hand if the cmake stuff will not be accepted for main fis-gtm distribution you will end up with a large patch set which is hard to maintain. It depends a bit what will happen with the final fis-gtm packaging where I do see two options: 1. Cmake based build will never require any running fis-gtm any more In this case I would really strongly hope upstream would accept this because this would be a really big simplification. 2. The Cmake stuff is only applied to get the initial packaging done and dropped later in favour to build all following fis-gtm packages using the previous fis-gtm as build-depends - in other words follow our original plan and just use cmake to circumvent the initial problems. This does not really require the acceptance from upstream for your changes. Both options would work (even if I'd regard 1. as the ideal one). However, if you try to apply the cmake patchset on top of every new fis-gtm source release I would not regard this as a sustainable solution for the future. In this case I'd rather tend to try to get plan B working. Hope this helps to make a good decision. For other more detailed advise I need more info. Your link to your github directory was not really helpful for me because if I prepend a "git clone" and try to download this repository this fails. Please be patient with me as a git beginner and explain how I can download the repository to enable me inspecting your changes directly (if you want me to do so - but I'm also no cmake expert and just cross fingers if I need to build a cmake based program).
