I loaded the following code into an XCode 7.1.1 project added the location
of crypto++ headers and libraries to their respective search paths. I then
added the crypto++ libraries libcryptopp.a and libcryptopp.dyld Link Binary
With Libraries list. The code compiled successfully and began running. I
then receive the following error:
*dyld: Library not loaded: libcryptopp.dylib*
* Referenced from:
/Users/arthur/Library/Developer/Xcode/DerivedData/cryptoppAES-bbtucachjqqaeediqkjywpllseec/Build/Products/Debug/cryptoppAES*

*The following error from Thread 1*
