opencv 4.7.0 in nixpkgs master has link errors #214124
Description
Describe the bug
Hi, I created a minimal demonstrator for my problem:
https://github.com/tfc/whiteboard-opencv/tree/without-aruco (not main branch but without-aruco, to also build with nixos 22.11)
This minimal C++ app includes and links against opencv4.
Building this flake using nix build works just fine and the resulting app works.
Running nix develop and then doing mkdir build && cd build && cmake .. && make results in link errors:
... many others omitted ...

Steps To Reproduce
Steps to reproduce the behavior:
- check out reproducer repo
- Run
nix build, works - Enter nix shell using
nix developand run:mkdir build && cd build && cmake .. && make, get mentioned error messages - Change flake input to nixpkgs 22.11
- Repeat step 1 & 2 and see that they work
Expected behavior
I would expect to not get these linker errors after upgrading to nixpkgs master
