  Build Directory:
    --builddir=DIR         place build files in directory [build]

  Installation Directories:
    --prefix=PREFIX        installation directory [/usr/local/zeek]
    --scriptdir=PATH       root installation directory for Zeek scripts
                           [PREFIX/share/zeek]
    --conf-files-dir=DIR   config files installation directory [PREFIX/etc]
    --localstatedir=PATH   path to store log files and run-time data
                           (within log/ and spool/ subdirs) [PREFIX]
    --spooldir=PATH        path to store run-time data [PREFIX/spool]
    --logdir=PATH          path to store log file [PREFIX/logs]
    --libdir=PATH          installation directory for library files [PREFIX/lib]
    --python-home=PATH     installation directory for Python module
                           [PATH/lib/python], the path tracks --prefix if
                           that option is used
    --python-prefix=PATH   versioned installation directory for Python module
                           [PATH/lib/python<Python Version>/site-packages]

  Required Packages in Non-Standard Locations:
    --with-pcap=PATH       path to libpcap install root
    --with-python=PATH     path to Python interpreter
    --with-python-lib=PATH path to libpython
    --with-python-inc=PATH path to Python headers
    --with-swig=PATH       path to SWIG executable

  Packaging Options (for developers):
    --binary-package       toggle special logic for binary packaging
    --ignore-dirs=PATHS    paths to ignore when creating source package
                           (semicolon delimited and quoted when multiple)
    --pkg-name-prefix=NAME use the given name as the package prefix instead
                           of the default CMake project name
    --osx-sysroot=PATH     path to the OS X SDK to compile against
    --osx-min-version=VER  minimum OS X version (the deployment target)

  Required Packages in Non-Standard Locations:
    --with-zeek=PATH        path to Zeek install root
