Refactored the location of cpp_clean when using CMake

[arango]

• Unified the location of cpp_clean in standalone ROMS and ROMS-JEDI for CMake configuration. In Compilers/roms_functions.cmake we now have:

  # Functions used in CMake to overcome its rudimentary capabilities.
  
  find_program(
    GREP
    NAMES grep egrep
    DOC "Grep command"
    REQUIRED
  )
  
  find_program(
    PERL
    NAMES perl
    DOC "Perl command"
    REQUIRED
  )
  
  find_program(
    CPP_CLEAN
    NAMES cpp_clean
    HINTS "${CMAKE_CURRENT_SOURCE_DIR}/ROMS/Bin/"
    DOC "ROMS CPP Clean command"
    REQUIRED
  )
  
  find_program(
    CPP_EXECUTABLE
    NAMES cpp
    DOC "C-preprocessor command"
    REQUIRED
  )
  
  message( STATUS "CMAKE_SOURCE_DIR=${CMAKE_SOURCE_DIR}" )
  message( STATUS "CMAKE_CURRENT_SOURCE_DIR=${CMAKE_CURRENT_SOURCE_DIR}" )
  message( STATUS "CPP_CLEAN=${CPP_CLEAN}" )
  

• Added CMake (cbuild_roms.csh and cbuild_roms.sh) scripts to all the applications in the test repository. As build_roms.csh and build_roms.sh, they can be used for any version of ROMS in the git and svn repositories.
