       Run Colm from the build directory. Use this when building from source
       and using the resulting binary without installing it. Colm will attempt
       to detect when it is run from the build directory. This flag lets the
       user be expliclit about it. The detection method is specific to the OS
       and can fail. The path given should be the root of the build directory,
       eg what would be returned by ABS_TOP_BUILDDIR (directory where src is).
