BAT Disable RooStats Dependency, 1.0 branch (2017.06.22.)
Turns out that it's not healthy to use the --enable-roostats
configuration flag for BAT after all. As it not only requires RooStats to be present, but also MathMore. And as ut turns out, MathMore can easily be left out of the ROOT build if the user doesn't have a number of required optional externals available. (I have now run into build problems on two separate platforms because of this in the last two days...)
Since the build proposed by the Top group also didn't use this flag, I guess it should be okay with them as well if I turn this off.
