I may just be generally struggling here because I never had to set up this before. Where do I see which header files are available?
After looking at other code examples I feel like `{.emit: "#include <gtk/gtk.h>".}` should work, but all I get is CC: ../../owlkettle/builder.nim /home/philipp/.cache/nim/scale_d/@m..@s..@sowlket...@sbuilder.nim.c:54:10: fatal error: gtk/gtk.h: No such file or directory 54 | #include <gtk/gtk.h> | ^~~~~~~~~~~ compilation terminated. Run Which means the corresponding code is not available of course, given how much gtk stuff I've got installed I was just convinced it was already there.
