%autosetup and conditional packaging

[Sérgio Basto]

Hi,

%autosetup -n GDCM-%{version} -S git -N
%patch1 -p1
%patch2 -p1
%patch3 -p1
%patch4 -p1
%patch5 -p1
%if 0%{?fedora} > 29
%patch6 -p1 -b .poppler.0.73.0
%endif

is this the correct way to apply one patch only in F30 ? , i.e. 
I need patch6 not be applied on F28 and epel7 how I do that when we are
using  %autosetup ?

Thanks,
