I truncated the bitbucket build to only build on ubuntu LTS 20.04.
Somehow all the other build targets - centos-7, centos-8, ubuntu-18 - have
an obsolete version of cmake. I do not know where the bitbucket os images
get these obsolete versions of cmake - my centos-7 and centos-8 have much
more recent versions of cmake.
If somebody has time to figure it out, please go at it, I would like very
much to have centos-7 and centos-8 builds restored (with ROOT), also
to have a ubuntu LTS 20.04 build with ROOT. (For me, debugging bitbucket
builds is extremely time consuming).
Right now many midas cmake files require cmake 3.12 (released in late 2018).
I do not know why that particular version of cmake (I took the number
from the tutorials I used).
I do not know what is the actual version of cmake that MIDAS (and ROOTANA)
I wish there were a tool that would look at a cmake file, examine all the
features it uses and report the lowest version of cmake that supports them.
