Asset import plugin `assimpsceneimport.dll` is not available on Qt 5.12.2 for Windows

I wonder why [asset import|https://github.com/assimp/assimp] library is not available for Qt 5.12.2 on Windows.

It should be noted that on Linux, asset import library is available for Qt 5.12.2

To show what I mean

On Windows, previous Qt releases like Qt 5.12.1 include asset import library, but that's not the case for Qt 5.12.2. I run these commands on WSL (Windows Subsystem for Linux):

 
me@LAPTOP:/mnt/c/Qt$ ls Qt5.12.1/5.12.1/msvc2017_64/plugins/sceneparsers/
assimpsceneimport.dll gltfsceneexport.dll gltfsceneimport.dll
assimpsceneimportd.dll gltfsceneexportd.dll gltfsceneimportd.dll

me@LAPTOP:/mnt/c/Qt$ ls Qt5.12.2/5.12.2/msvc2017_64/plugins/sceneparsers/
gltfsceneexport.dll gltfsceneexportd.dll gltfsceneimport.dll gltfsceneimportd.dll
