To clarify, there is no difference between Qt "dev libs" and "end user
libs". They are one and the same.

OK, to be pedantic, developers also have Debug versions of each
library, which you would not give to an end user. The Release versions
of the "dev libs" are the ones that get packaged into apps' .deb files
-- these can also be copied directly to the deployment machine along
with your app executable, if you don't want to use a package manager.
