cmake: improve building on mac

previously some libraries weren't found on MacOS if they weren't
force-linked using brew link.
This patch makes cmake discover the libaries in their respective
directories under /usr/local/opt/ so linking is not required anymore.

We also change the linking with homebrew libraries to be static instead
of dynamic so you don't need to install homebrew to use bareos.

Lastly this fixes a build issue when you have a case-sensitive
filesystem.
