Fall back to CMake's pkg-config-based search for curses

Browse Source 
CMake seems to have trouble finding libraries from multiarch packages
that do not have the compatibility symlink installed to the
arch-independent library directory. Users must either manually supply
the path to the library in question via command-line parameters or we
can fall back to CMake's alternate method of finding packages based off
of pkg-config rather than using the hard-coded `FindCurses` CMake module
specific to the CMake version/distribution installed.
