On Windows, the standard library translated all LF bytes in the binary
stream to CR+LF...

Thanks to Vítek ;)

The problem was the getRow() method, there is only getRowFast() which
does not work cross-device.

I'm assuming that the 'GridEntityCrossStencil' enum constant was cast to 1

This does not need any code in cmake as the macro is defined by the
compiler itself. See also the table here:

Among other things, this shortens the output to the console and speeds
up the build.
