Compilation errors after MELA v2.1.0 release

[mmusich]

Dear all,
@clacaputo @Meriem123 and I are using a slightly changed version of this framework.
I would just like to point out that recently we've started getting compilation errors after the release of the new MELA version when using the recipe in https://github.com/cms2l2v/2l2v_fwk/blob/master/README.md (for 80x):

since MELA is not used in our analysis we can revert to an earlier version and ignore the issue, but I am propagating the info as suggested by @amagitte just in case...
Best,
