When doing a VPATH build from a fully clean checkout, the GOB outputs
end up in the build directory. When this happens, #include "pcx.h"
won't find the header because this header is in srcdir.
The solution is to make sure we always #include relative to the top
src/ directory, which is already explicitly added to the compiler
search path.
#include <uobject/loadable.h>
#include <uobject/exportable.h>
#include <engine/palette.h>
-#include "pack.h"
-#include "pcx.h"
+#include <engine/pcx.h>
+#include <pack.h>
%}
