  Optional options:
     [no option]        build all components
     --fe               build Frontend and Spark DPP application
     --be               build Backend
     --meta-tool        build Backend meta tool
     --broker           build Broker
     --spark-dpp        build Spark DPP application
     --hive-udf         build Hive UDF library for Spark Load
     --java-udf         build Java UDF library
     --clean            clean and build target
     -j                 build Backend parallel

  Environment variables:
    USE_AVX2            If the CPU does not support AVX2 instruction set, please set USE_AVX2=0. Default is ON.
    STRIP_DEBUG_INFO    If set STRIP_DEBUG_INFO=ON, the debug information in the compiled binaries will be stored separately in the 'be/lib/debug_info' directory. Default is OFF.

  Eg.
    $0                                      build all
    $0 --be                                 build Backend
    $0 --meta-tool                          build Backend meta tool
    $0 --fe --clean                         clean and build Frontend and Spark Dpp application
    $0 --fe --be --clean                    clean and build Frontend, Spark Dpp application and Backend
    $0 --spark-dpp                          build Spark DPP application alone
    $0 --broker                             build Broker
    $0 --be --fe --java-udf                 build Backend, Frontend, Spark Dpp application and Java UDF library

    USE_AVX2=0 $0 --be                      build Backend and not using AVX2 instruction.
    USE_AVX2=0 STRIP_DEBUG_INFO=ON $0       build all and not using AVX2 instruction, and strip the debug info for Backend
