"make package" is convenient for making a .deb. Currently the .deb depends on the "python" package but in 20.04 it makes things complicated. Does anyone else install LyX with locally built debs?
The attached patch seems to work well. Kornel, OK to commit? Scott

Subject: [PATCH 3/6] CMake deb: support "python2 | python3" dependency
The latest debian-based distributions have moved away from
the "python" package dependency to "python2" and "python3".
