[CMake] SPECIFYING THE DEPENDENCY BETWEEN NON-C FILES

[Oh K]

Hello,

I wonder if someone can help me with specifying the dependency rules
between inexistent files.

The situation is as follows: A header file named 'H-a.h', is supposed
to be created by an extenal tool named T using the other file named
'F-a.txt' during the build process.  Of course, there is a c file
named 'C-a.c' dependant to 'H-a.h'.  I know there is a dependency
between 'H-a.h' and 'F-a.txt', while there is no such file, 'H-a.h'
before the beginning of a build.  I tried SET_SOURCE_FILES_PROPERTIES
like SET_SOURCE_FILES_PROPERTIES(H-a.h PROPERTIES OBJECT_DEPENDS
F-a.txt)'.  However, I continue to fail to generate a dependency rule
between these 2 files.  I think it does not work because the H-a.h is
not an object file.

I wonder if there is some proper ways to create the dependency rule
between non-C files.
