MumbleKit.framwork not found

[khawarb]

I have configured MumbeKit by following below instructions,

1. Make MumbleKit (iOS) direct dependency of your application's main executable target.
2. Drag libMumbleKit.a into the 'Link Binary With Libraries' section of your application target's build phases.
3. Add MumbleKit's src directory as a header search path for your application's main executable target.
4. Add MumbleKit's dependencies as linked libraries to the executable target:
   AudioToolbox.framework
   CFNetwork.framework
   Security.framework

Now when i build the projects it's giving below error

clang: error: no such file or directory: '/Users/Macbook/Library/Developer/Xcode/DerivedData/My_App-awhiyxuwstbqvwbrpddkaxcffoaj/Build/Products/Debug-iphonesimulator/MumbleKit.framework/MumbleKit'

And MumblKit.Framework is red in project files, how i can find this MumbleKit.framwork?
