The default generator is Unix Makefiles for most platforms, but this
lets the builder easily select a different build framework depending
on their platform (e.g. Xcode, CodeBlocks, Eclipse ...)
Made order of --enable-broctl and --enable-cluster not matter.
--enable-cluster always enables Broctl in cluster configuration even if
the other option is used.
--enable-broctl will enable Broctl in standalone configuration only if
--enable-cluster isn't present.
To POLICYDIR since that's more clear. Also decided that restricting
it to a subdirectory of prefix isn't much use as an option, so went
back to having it be an absolute path.
- configure wrapper had bash syntax some places; replaced w/ sh syntax
- Added FindOpenSSL module. The one that ships with CMake does not
allow for specifying a non-standard location.
- datadir configure option changed to be relative to prefix. This
simplifies the packaging from having to consider absolute paths.
- Added macro for changing install_name of shared libs that need to
ship with precompiled Bro for OS X. This is only the optional
libmagic and libGeoIP for now.
