# Copy the generated lib files (they are in `build/code`) into `~/develop/webots/lib`, for example, on macOS:
cp code/libassimp.dylib ~/develop/webots/lib

make assimp -j X

On macOS you will need to add to cmake:

-DCMAKE_OSX_ARCHITECTURES=x86_64 -DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk -DCMAKE_OSX_DEPLOYMENT_TARGET=10.9

and change RPATH once copied in Webots:

cd ~/develop/webots
install_name_tool -id @rpath/lib/libassimp.dylib lib/libassimp.dylib

Create the package

tar -cvjSf assimp.tar.bz2 assimp/include/assimp assimp/build/include/assimp/config.h assimp/build/code/*dylib
