Hello,
I think I found the answer: it is only when actually building the
program that the source files get scanned and therefore the depend.make
file gets filled. That, of course, does make sense.

Hello,
I am trying to create CMake-based build system for a program
that uses both C and Fortran source files. While expanding the
CMakeLists.txt files to include a custom build step for one
C header file, I stumbled on something I do not understand.
The makefiles generated from my first versions did not seem to
include any dependencies from #include (the file "depend.make" was
simply a dummy).
When I added my custom build step, I had great difficulty to get
the dependencies right. The file "depend.make" remained empty.
Then I added a call to set_source_files_properties() to explicitly
set the dependency on that one header file and now I see that
_all_ C files in the project are listed there.
So, my question: is it the set_source_files_properties() command
that turns on this scanning? Is there a more explicit way (I want
to have this scanning turned on regardless of any explicit
dependencies I need).
I am using CMake 2.8
Regards,
Arjen
