library not found for -lcrypto #14

hello

when i use this and create libcrypto.a from the openssl-xcode project, it is fine.

but i create workspace and follow the build step, the Xcode give me a error.

ld: library not found for -lcrypto
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Do you know how to fixed it?
I am sure that library path and header path is correctly.

thank you.
