No, that does not help. Neither header file nor library will be found in 
my cross environment without using the provided --extra-cflags and 
--extra-ldflags, because all those files are installed below 
/usr/i686-w64-mingw32/sys-root/mingw or 
/usr/x86_64-w64-mingw32/sys-root/mingw which is not searched by the 
default compiler settings. The Meson checks obviously don't use those flags.

pkg-config provides the right paths and works therefore.

Of course I can manually fix my cross environment and move or link all 
header and library files to standard directories, so they will be found. 
But then I'd suggest to remove --extra-cflags and --extra-ldflags 
because they promise something which they don't provide. I think that 
full support for both configure options would be better.
