[GNC-dev] recent CMake warnings

[Geert Janssens]

Hi Frank,

I had a quick look at this.
I don't know what to do with your eclipse warning. That's not part of our CMake 
configuration. I suppose you are using something like -G Eclipse-CDT or something when 
you call cmake.

For the python warnings I have pushed a small change to use the newer find package 
module to detect python when our cmake is 3.12 or more recent.
As our baseline is still 3.10, I have kept some compatibility code for older cmake versions.
If however we choose to support Ubuntu 20.04 LTS as oldest distro, we could set cmake 3.16 
as baseline and then the compatibility code could also be dropped. Ubuntu 18.04 LTS has 
reached end of standard support in May 2023, so IMO that's something we could consider.

Regards,

Geert
