'configure' configures Locksmith to adapt to many kinds of system.

Configuration:
  -h, --help              display this help and exit
  -V, --version           display version information and exit
      --srcdir DIR        find the sources in DIR
      --debug-build       create a debug (rather than release) build.

Installation directories:
  --prefix PREFIX         Set CMAKE_INSTALL_PREFIX.  Default $install_prefix_default

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
