I'm used to the linked .dlls showing up in the output directory.
This doesn't seem to happen for assimp.
I have no idea whether I'm calling things wrong,
this is a problem in assimps .cmake or a packaging/porting issue in vcpkg.

I've attached a small repro project - you'll probably have to adapt build.cmd for things to work.
repro.zip

build.log contains the output build.cmd produces on my machine.

EDIT:
the test project depends on protobuf:x64-windows assimp:x64-windows to be installed.
