Which Version?

[NierAimer]

sry my bad i mean aasimp release assimp-5.2.4,i ues the .dll and .lib to make plugin,when i use cmake to build assimp shows pkg-config and zilb not found

[kimkulling]

Seems to be perfect. The issue you have mentioned is just a hint that the own zlib will be used. To fix the other issue:

• Look for the zlib-installation from OpenCV
• Add this to your environment. On StackOverflow you will be able to find more information
