Options: -full, -regular_latlon, -debug, -dev, -prod(default)

Example 1: Default compilation of LMDZ-ORCHIDEE with XIOS and IOIPSL
./compile_lmdzor.sh

Example 2: Compile in debug mode
./compile_lmdzor.sh -debug

Example 3: Default compilation with full recompilation of all components
./compile_lmdzor.sh -full

Example 4: Compilation of LMDZ in regular lat-lon for other dimensions (default: 144x142x79) 
The dimension can be changed to any other 3d dimension.
./compile_lmdzor.sh -regular_latlon 96x95x79
