Possibly (at least you would if this was for KDE).
In KDEs build files cmake itself is also called from the makefiles, not only 
for generating makefiles, but also e.g. to execute scripts, copy files, 
create directories, and other things we are otherwise not portable between 
different OSs.
With "cmake -E" you can do such things in a portable way, or you can run 
simple scripts via "cmake -p", in both cases embedded as COMMAND in 
add_custom_target() or add_custom_command().

Also, cmake itself is used for generating the C dependencies. I don't know 
what happens if you don't have cmake around.

So, as the others say, consider cmake a part of the toolchain which must be 
installed on the building host.
