Describe the bug

I tried to install the rpm package on quite fresh (2 Weeks old) installation of OpenSUSE.

Running:

sudo rpm -i appimagelauncher_3.0.0-alpha-4-gha275.0bcc75d_x86_64.rpm

fails with:

error: Failed dependencies:

[MaKaNu]

Well one workaround I found out:

zypper install --allow-unsigned-rpm appimagelauncher_3.0.0-alpha-4-gha275.0bcc75d_x86_64.rpm

I am not sure if this is rpm's fault, but the error message doesn't really provide the hint, that 32Bit packages are needed.

[TheAssassin]

The packaging specifies the dependency using library names rather than actual package names as those may vary across RPM-based distros (in the Debian/Ubuntu land, things are more consistent):

export LDNP_META_DEB_DEPENDS="systemd, libgl1, libfontconfig1, libharfbuzz0b, libfribidi0"
# vs.
export LDNP_META_RPM_REQUIRES="systemd libGL.so.1 libfontconfig.so.1 libfreetype.so.6 libfribidi.so.0 libgpg-error.so.0 libharfbuzz.so.0"

I am not sure why RPM wants to install 32-bit dependencies, though. Maybe there is a way to specify the architecture here? Would be annoying, but less annoying than distro-specific packages.
