A more long-term solution would be for cmake to understand the concept of 
compile farms.

In any case, I have solved this problem locally for more than 2 years. The 
attached program is what I use. It's a small LD_PRELOAD module that will 
enslave the execution of some programs to the scheduler. It has "tb" hardcoded 
because I wrote it for Teambuilder, but changing it to Icecream is trivial 
(findInPath("tb") to findInPath("icecc")).

To use:
- build it and put it somewhere known (like $HOME/bin)

- add to your ~/.profile, ~/.bashenv or similar script:
	export EN_TB=moc:uic:uic3:meinproc4:qmake:automoc4

- ensure you have LD_PRELOAD set to the script when compiling, like for 
example this function in ~/.profile or something
	function make() {
		export LD_PRELOAD=$HOME/bin/en-tb.so 
		command make "$@"
	}
Or if you have a make-replacement script, add to it.
