In General I agree. thats is why ultimately I would like cmake to support 
creating of csproj files.   That would need to be implemented,  but has already 
been proven possible by cmakes other VS proj support.

For this project I don't believe that maintaining cmake will be all that 
difficult.  it supports wildcards (Dir/*.cs) when selecting which files to build 
which means that in most cases no changes will need to be made.  There is an 
exception to this which im planning on raising in a separate thread.  
Currently that work I have done with cmake has encountered a large number of 
"abandoned" files within the repo.   It seems these classes have been migrated 
into System.* but only removed from the proj file.   This is really really 
messy.

Nope it calls the compiler directly.   Sadly I think it would be very difficult 
to maintain xbuild to do what I want it to do.  Ultimately we need to get the 
Runtime/ directory out of the tree (or at least make linking against it 
optional).  There are also other benefits.

* It also makes pkg-config support very easy.
* Allows multiple (as many as you want) out of tree builds so that you can for 
example run tests on standard debug build as well as a silverlight build 
simultaneously.  You also don't have to be constantly switch configs. you can 
easy target multiple versions of mono/.NET etc etc etc.
* supports creating of debs and rpms directly.
