[Openflipper] MeshIntegration not found

Hello, I noticed the message "Could NOT find MeshIntegration (missing: MESH_INTEGRATION_INCLUDE_DIR)" in the output of the cmake file. I searched for such a package online and didn't find anything specific. Where can I find this package, and what does it do? I still managed to install openflipper, however I can't get the viewport to display any mesh. Might the lack of the package cause this? Thanks, Azur Ponjavic
