This must be done differently.
The command is executed during the build, calling a macro gets executed during
cmake time, so you can't add a dependency to it.
Instead you probably need an additional custom command, which has as output
the ical.h file, and which calls cmake with a cmake script file, as it is
done in KDE4Macros.cmake with kde4uic.cmake.
