[CMake] SPECIFYING THE DEPENDENCY BETWEEN NON-C FILES

[Oh K]

Kris and David,

I have checked and tried the documentation.  It works when I run the
commands with cmake 2.0.6, while it doesn't with cmake 2.2.1 beta.  I
had first tried it with cmake 2.2.1 beta and it continues to fail to
generate a proper Makefile as ADD_CUSTOM_COMMAND documentation says as
below:

In makefile terms this creates a new target in the following form:

  OUTPUT: MAIN_DEPENDENCY DEPENDS
          COMMAND

I personally prefer the new forms of the generated directories and
Makefiles by the version 2.2.1 beta to the forms by the previous
version.  However, it is still in beta and I may need to report this
as a bug and stay longer in the use of the version 2.0.6 yet until
cmake 2.2.1 becomes more complete.

Anyway, thank you for your helps and comments.

K Oh
