ALLOW_CXXFLAGS_OVERWRITE

Setting this option will allow you to overload preprocessor definitions from the command line, as it was possible naturally with the autotools build system. This feature only works with a Unix Makefiles based generator. You can use it as:

make CXXFLAGS="your flags" GRIDTYPE="grid type"

GRIDTYPE can be anything defined in config.h via the dune_define_gridtype macro from dune-grid. Furthermore any CPP variable of the form -DVAR=VALUE can be overloaded on the command line.

Note

If you don’t know what this is or what it’s good for, don’t use it.
