Serializing possibly resource-intensive tasks such as meinproc

[Allan Sandfeld Jensen]

Hi Lubak

This is an excelent idea (I've tried convincing Dirk to do something similar 
for years).

But why are you detecting icecream and adding in cmake? Wouldn't it be better 
to simple add a meinproc link during icecream installation like it is done for 
cc and c++?
