%filter_requires_in prevents the matching files from being scanned for

The way dynamic linking works is that every elf binary has DT_NEEDED
entries for libraries it needs at runtime. RPM scripts extract that info
from binaries and store it in the RPM metadata. Now, %filter_requires_in
prevents the matching .so files from being scanned by rpm dependency
extracting scripts, so anything these .so files might need will be lost.

Try this:
%filter_from_requires /cvisualmodule\.so/d

Hope it helps,
