Sample code from my attempts might help:
mkdir -p $out/
cp -r $src/* $out/
chmod 777 -R $out/*
patchelf --interpreter "$(cat $NIX_CC/nix-support/dynamic-linker)" \
--set-rpath $libPath:$out/lib \
$out/bin/cnijnpr
ln -sv $out/lib/libcnbpcmcm356.so.8.0.1 $out/lib/libcnbpcmcm356.so
LIBTIFF=$(pkg-config --libs-only-L libtiff-4 | sed -e
's/-L//g')/libtiff.so.5
ln -s $LIBTIFF $out/lib/libtiff.so.4
ldd $out/lib/cups/filter/pstocanonij
The latter looks inside the binary and tries to link it (dynamically) - it
should show what's still missing. The tiff business just makes tiff
available to the canon driver.
The rpath bit in the patchelf command is probably what you're looking for
initially.
