You should be able to just drag the file from the Finder into "Linked 
Frameworks." Xcode is smart enough to statically link such things 
automatically.

However, if it's in /usr/local/lib, I assume you want it to actually 
reside in the Framework bundle at runtime (so that the user doesn't 
have to install the library)? Here's what I did for my framework:

1. In the Finder, copy the libcurl.a file to your project directory
2. Drag the file from the project directory to "Linked Frameworks" in 
the Xcode window
3. Choose "relative to enclosing group" (the default should be fine)

If you want the library bundled in the framework, you'll also have to 
add a copy phase (Project > New Build Phase > Copy Files Phase). The 
new copy phase should be visible when you click the triangle next to 
your active target. Drag the file from the Frameworks group to the copy 
phase, then open the inspector and choose "Frameworks" as the 
destination.

If you want a working example, download the DataCrux source from

This caused me a few problems initially, so let me know if you can't 
get it working. More here too:
