Linker errors with CImg and libtiff on Xcode

Question

I can't get libtiff to successfully link for an application that uses CImg.

I've installed libtiff with brew, nothing, compiled libtiff from sources and installed still nothing (where's the libtiff.a after compilation btw?) I've added the path in XCode but still cannot get it linked. In other linker flags: /usr/local/lib/libtiff.a but still nothing. I get a lot of:

Ok I've solved it. I had to do all of the processes again: download libtiff, use CMake to generate the appropriate configuration files for my system, (unix makefiles) and from there, just a console make and make install and they were correctly installed in my system so Xcode finally could see them. I guess CMake was the hero here because the ./Configure was useless before.
