I have removed the `MESON=...` part and automatic download of meson 
works then.

But now it breaks with
C:\BuildLO2\core\vcl\inc\skia/utils.hxx(34): fatal error C1083: Cannot 
open include file: 'SkRegion.h': No such file or directory
make[1]: *** [C:/BuildLO2/core/solenv/gbuild/LinkTarget.mk:338: 
C:/buildLO2/core/workdir/CxxObject/vcl/win/gdi/salnativewidgets-luna.o] 
Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:301: build] Error 2

It seems that it tries to so something with Skia, but I have 
--disable-skia for autogen.sh. I know Skia does not build for me with 
Cygwin.

I want to build with WSL, because there building with Skia worked. But 
with the new harfbuzz things, build with WSL works neither, see my other 
mail.

Kind regards,
Regina
