Missing FindCarbon.cmake

[Nicolás Alvarez]

I'm trying to build KF5 on OS X. KIdleTime, KWindowSystem and KWallet
depend on the Carbon library; they have a find_package(Carbon).
However, they all fail to find FindCarbon.cmake. It's currently
present in kde4support and in the ecm 'attic' directory. Should it be
installed by ecm, or copied into the frameworks that need it?

On another note, Carbon is deprecated, so if any Mac guy could port
things to Cocoa... :)
