Setting CMAKE_PREFIX_PATH helps link against standard system libs
instead of ones that come from other package manager (e.g. MacPorts).
Changed to allow only more recent CMake versions to create packages
due to poorer clang compiler support in older versions, important
since clang is now the default compiler instead of gcc on Macs.
- Now requiring CMake 2.8.6
- Make moving of packages into build/ independent of package names.
- Bro-all package renamed to Bro and Bro renamed to Bro-minimal
which is more similar to source packages now.
- Move binary packaging scripts out of source root into pkg/ subdir
- A consistent CMake version (2.8.4) is now enforced for binary packaging
- Added a 'bindist' target to top Makefile as a convenience
- The 'dist' target has been rewritten to depend on standard system
command/utils rather than CMake and the full dependency chain of Bro,
addressing #398 (but the CMake 'package_source' target is still available
in the generated build/Makefile and can be used if desired)
