DIET's advanced configuration flags

Eventually, some configuration flags control the general result of the compilation or some developers extensions:

• BUILD_TESTING is a conventional variable (which is not a cmake internal variable) which specifies that the regression tests should also be compiled.

• BUILD_SHARED_LIBS is a cmake internal variable which specifies whether the libraries should be dynamics as opposed to static (on Mac system this option is automatically set to ON, as static compilation of binaries seems to be forbidden on these systems)

• Maintainer By default cmake offers four different build modes that one toggles by positioning CMAKE_BUILD_TYPE built-in variable (to Debug, Release, RelWithDebInfo and MinSizeRel). Maintainer is an additional mode which fulfills two basic needs of the task of the maintainer of DIET. The first preventive task is to provide code free from any compilation and link warnings. The second corresponds to the snafu stage which is to debug the code. For reaching those goals the Maintainer build type sets the compilers flags, respectively the linker flags, with all the possible warning flags activated, resp. with the additional debug flags.

• Several options (not accessible through the ccmake GUI) can control the installation paths for libraries, binaries, includes and modules. By default the value of these install paths are respectively ${CMAKE_INSTALL_PREFIX}/lib${LIB_SUFFIX}, ${CMAKE_INSTALL_PREFIX}/bin, ${CMAKE_INSTALL_PREFIX}/include, ${CMAKE_INSTALL_PREFIX}/share/cmake/Modules. They can independently be set up using the following variables LIB_INSTALL_DIR, BIN_INSTALL_DIR, INSTALL_INSTALL_DIR and CMAKE_MOD_INSTALL_DIR. You can set those on the command line when calling cmake or ccmake, for example cmake .. -DLIB_INSTALL_DIR=${HOME}/lib.
