Loading framework in Polycode Xcode project

Loading framework in Polycode Xcode project

I have what could be a very obvious problem when trying to load a
framework in a Polycode (C++ gaming library) Xcode project.
I locate the library in the file that its in, in finder. Then drag and
drop into the Framework file in the left hand column in Xcode- a dialogue
box comes up and I click ok. It's there in linked frameworks in the
general tab, and in build phases. It's in the frameworks folder on the
left. Press build and I get;
ld: warning: directory not found for option
'-L"/Users/user/Documents/Polycode/Release/Darwin/Framework/Template/Xcode/../../Core/Lib"'
ld: warning: directory not found for option
'-L"/Users/user/Documents/Polycode/Release/Darwin/Framework/Template/Xcode/../../Dependencies/Lib"'
ld: warning: directory not found for option
'-L"/Users/user/Documents/Polycode/Release/Darwin/Framework/Template/Xcode/../../Core/Dependencies/lib"'
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Anyone know what I'm doing wrong?
