 The first two flags `--host=$LUNA_ARCH-luna --prefix=/usr` are required if using a standard configure script, to indicate that we're cross-compiling (compiling the program for another system).
 
 Alternatively, you can simply set `use_default_configure=true` without a `do_configure` function, which will simply run the configure script with these two flags, if you don't need anything else.
+If using CMake and not needing any extra parameters, setting `use_cmake_configure=true` will have the same effect.
