Running rpm-setup.sh shows missing packages that Centos does not need

Summary

When running rpm-setup.sh --install-optional on Centos8.5, it prompted missing packages which Centos does not need.

This issue does not exist in 3.0.0, and in newer versions(3.4.12 upward, I have tested 3.4.12 and 3.7.x) this issue exists.

Using dnf (info)
update-desktop-files is unavailable
cap progs are unavailable
....

If related package lines are removed from rpm-setup.sh, building works properly.

=== removed package lines in rpm-setup.sh ====

# This in only required (and available) on OpenSUSE
add_package BASIC_LIST update-desktop-files ||
echo "update-desktop-files is unavailable" >&2

add_package ADDITIONAL_LIST libcap-progs || echo "cap progs are unavailable" >&2

Steps to reproduce

wget https://2.na.dl.wireshark.org/src/wireshark-3.4.12.tar.xz
tar xJf wireshark-3.4.12.tar.xz
mkdir build
cd build

sudo ../wireshark-3.4.12/tools/rpm-setup.sh --install-optional
