[Pkg-cmake-team] Bug#945825: 945825: persists with the next iteration of Python versions

[Andrius Merkys]

control: affects -1 src:openstructure
control: found -1 3.18.4-1

Dear maintainer,

The problem persists with the next iteration of Python versions.
Specifically, I have both Python 3.8 and 3.9 are installed, cmake does
not find the development files of Python 3.8 and fails if not 3.9
development files are installed. Observed when building
openstructure/2.2.0~rc.

Best,
Andrius
