Build failure with USE_LIBRAW=OFF

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Every other optional image loader (OpenEXR, WebP, JPEG XL, AVIF, HEIF, GraphicsMagick, ImageMagick) falls back to _unsupported_type when its library isn't built in, but dt_imageio_open_libraw is missing that guard.

Steps to reproduce

build with USE_LIBRAW=OFF

Expected behavior

should build

fix could be as simple as adding the following lines to imageio.c:

#ifndef HAVE_LIBRAW
#define dt_imageio_open_libraw _unsupported_type
#endif

Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip

No response

Start in imageio.c and inspect the existing guards for optional image loaders alongside dt_imageio_open_libraw. Build darktable with USE_LIBRAW=OFF on the reported Windows/MSYS2 setup and confirm the build succeeds without the LibRaw loader.
