[CMake] Using Intel Integrated Performance Primitives (IPP) in CMake

[Mike Jackson]

Just a slow day while we wrap some things up and I was looking  
through the Intel IPP documentation and there are a whole slew of  
optimized string functions that come with the Intel C++ compiler. I  
was wondering a few things about using these within cmake (since  
cmake seems to be parsing lots and lots of strings).

1) Has anyone tried out the IPP string functions to see if they  
really do generate faster code
2) If no one has, what would be a good place to try these functions  
out? I am looking in cmSystemTools at the moment. In other words,  
what would be the "low hanging" fruit to try and optimize with these  
functions (if any more optimization can be done)?
3) How much friction would there be to have these as an option in the  
cmake code base? For those of us with the Intel C++ Compiler at our  
disposal?

4) Is the string parsing really any sort of bottle neck in the first  
place?

Again, just a slow day and was curious. Comments welcome...
