if If auto, CMake will try to enable the feature, but will not fail if it can not.
To make sure that a feature is really enabled, you will have to specify with the otion option ex: -DENABLE_GRIB=ON. In that case CMake will fail if the grib support can not be enabled.
...
The options to enable/disable output formats allow you to customise your installation. For example, if you have problems on your system with support libraries (see previous section), you might want to try to disable the raster output. Cairo libraries are responsible for most third-party dependencies.
Compiling the code
After the CMake command has run successfully, the user can compile the library by typing make in the build directory.

Quick installation guide
This is an example of a list of commands needed you could use to install Magics. It is assumed “>” is the shell prompt. The Magics version number may vary.
>mkdir magics
> mkdir build
>tar > tar -xzf Magics++-2.22.0.tar.gz
>cd build
> cd Magics++-2.22.0
> mkdir build ; cd build
> cmake .. >cmake –DCMAKE_INSTALL_PREFIX=/path/to/where/you/install/Magics++-2.22.0
