I finished my mac app using Xcode and Qt. Now I would like to prepare it for deployment to other macs. Inorder to do that I utilized macdeployqt.
I just created an app bundle with macdeployqt. However some of the libraries are missing. I attempted to follow [this][1] answer. Turns out I need to copy the missing dylib from my computer to the .app and then run install name tool. I have not gotten to the install-name tool yet as I am confused as to use -id or -change with it especially in my current scenario. Do I even need to use it ? Here is what I did so far.
Step 1: Running macdeployqt - this is a program that comes with Qt and embeds the necessary requirements of qt into the app.
> /Users/Guest/Qt/5.5/clang_64/bin/macdeployqt project2.app
Step 2: I then decided to run otool on the actual generated app binary
> pwd
/Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS
> otool -L project2

Step 3: However I noticed that my project2.app/Contents/Frameworks does not have those libraries inside them. So I decided to copy them manually.
cp /usr/local/lib/libosg.141.dylib project2.app/Contents/Frameworks/libosg.141.dylib
cp /usr/local/lib/libosgDB.141.dylib project2.app/Contents/Frameworks/libosgDB.141.dylib
cp /usr/local/lib/libosgGA.141.dylib project2.app/Contents/Frameworks/libosgGA.141.dylib
cp /usr/local/lib/libosgUtil.141.dylib project2.app/Contents/Frameworks/libosgUtil.141.dylib
cp /usr/local/lib/libosgViewer.141.dylib project2.app/Contents/Frameworks/libosgViewer.141.dylib
cp /usr/local/lib/libosgManipulator.141.dylib project2.app/Contents/Frameworks/libosgManipulator.141.dylib
cp /usr/local/lib/libOpenThreads.20.dylib project2.app/Contents/Frameworks/libOpenThreads.20.dylib
Could you tell me what my next steps should be after copying those files ?
This is the output that I get when I attempt to run the app on another computer without using install_name_tool
Dyld Error Message:

Update:
After some struggling I decided to do the following
install_name_tool -change libosg.141.dylib @executable_path/../Frameworks/libosg.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
install_name_tool -change libosgDB.141.dylib @executable_path/../Frameworks/libosgDB.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2

install_name_tool -change libosgViewer.141.dylib @executable_path/../Frameworks/libosgViewer.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
install_name_tool -change libosgManipulator.141.dylib @executable_path/../Frameworks/libosgManipulator.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
install_name_tool -change libOpenThreads.20.dylib @executable_path/../Frameworks/libOpenThreads.20.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
That did not seem to solve the problem as when I did this to one of the libraries that I just had added.
otool -L libosgDB.141.dylib

I am still not getting paths for the libraries libOpenThreads.20.dylib , libosgUtil.141.dylib and libosg.141.dylib any suggestions would be more than welcome.
libosg.141.dylib is a dylib that you're including in your built app.
You should actually look in your app's binary... that is:
otool -L /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
As for resetting the path of the library to point to "@executable_path/../Frameworks/libosg.141.dylib" instead of the dylib in "/usr/local/lib", try doing this:
install_name_tool -change libosg.141.dylib @executable_path/../Frameworks/libosg.141.dylib /Users/Guest/project_XCODE/bin/Release/project2.app/Contents/MacOS/project2
