[Solved] Pacman create symlinks not present in package

I wish to create an additional Embree package that could reside alongside main repository one.
The main repo package provides those libs/symlinks

embree /usr/lib/libembree.so
embree /usr/lib/libembree.so.2
embree /usr/lib/libembree.so.2.17.0

and here is my embree-bvh_build-git PKGBUILD  and patch that rosolve conflicts.
My package provides single lib (plus headers and cmake script)

embree-bvh_build-git /usr/lib/libembree.so.2.8.0

Problem ocures when I try to install first my embree-bvh_build-git and than official embree packages from the arch repository.
Pacman complains about /usr/lib/libembree.so.2 existing in current tree and aboard the installation. This symlink is reported to not belong to any package pacman -Qo /usr/lib/libembree.so.2 and gets created at install time for my embree-bvh_build-git package.
Reversed order of installation, embree>embree-bvh_build-git doesn't have this problem.

I assume that Pacman creates this symlink automatically, is this intended behavior, is there a way to control this behavior creation by package scripting?

Pacman isn't creating the symlink, ldconfig is. If it doesn't find a symlink matching the soname, it creates it.

Thank for the tip, first time I heard about soname. Already include it in my patch witch cmake target property SOVERSION Now everything works as expected.
Again, thanks for pointing me in the right direction!
