  script to build under docker

  Step: 
   1) clean old build directory
   2) create image builder
   3) launch build under docker (launch script build-under-docker.sh)
   4) remove docker container with state exited

options:
  -h, --help       : Show this help
  -d, --debug      : Show debug message
  -r, --remove     : Remove old build repository
  -f, --force-create-image : force to create docker image (use to build khanat) - default autodetec.
  -j [N], --jobs[=N]          Allow N jobs at once; infinite jobs with no arg.
  -a OPTS, --add-opts-cmake=OPTS : Adding options on cmake command (before build)
  -c, --clean-container : remove all container in state Exited
  -w, --clean-images-none : Remove images docker (with name 'none')
  -m OPTS, --add-opts-docker=OPTS : Adding options on docker command (when build)
  
Example :
  cd [root Khanat directory]
  ./build.sh -c -r
  ./build.sh -c -r -j 4 -a '-DWITH_SYMBOLS=ON' -a '-DWITH_RYZOM_TOOLS=OFF' -a '-DWITH_NEL_TOOLS=OFF' -m '-m 20g'
