As mentioned in a different bugreport [0], c4core depends on biojppm/cmake, debugbreak, and fast_float. To meet the dependency, we're now preparing for uploading debugbreak and fast_float [1][2].
As for biojppm/cmake, it looks like this software is used for the author's project only. This makes me wonder if it is really reasonable to package biojppm/cmake. It is technically possible to package it but it could end up with no other packages depending on the packaged biojppm/cmake than c4core. To make a clear decision, I would like to ask for your opinion on this issue.
