Mike,

I don't know who or what "Gnucash - Dev" might be. If it's our gnucash-devel mailing list then you need to subscribe at https://lists.gnucash.org/mailman/listinfo/gnucash-devel before you can post.

It's generally more useful to act on the errors CMake writes to terminal as it runs and leave the log files for digging into details if the cmake output is anomalous. The snippet above looks like it's just part of the normal cmake compiler and standard library probes and doesn't necessarily indicate a problem.

That said, Centos doesn't support GnuCash and several of its dependencies so getting GnuCash running there is more difficult on distros that do. Are you currently running GnuCash, presumably without Python bindings, on Centos?

Regards,
