[CMake] CMake will not be able to correctly generate this project.

[Mike Jackson]

I think you might be missing a very basic tenant of CMake: Out of  
Source Builds. CMake creates a pile of files and all the compiler  
output and all that sort of stuff _really_ needs to be gathered into  
it's own directory. The way you are running it currently, all those  
files will be put loose into your home directory. Try this:

[root at localhost ~]# cd /home/gregory/tarballs/canorus-0.5beta.R682
[root at localhost ~]# mkdir Build
[root at localhost ~]# cd Build
[root at localhost ~]# cmake ../
[root at localhost ~]# make

And lets see what happens..
