[CMake] Source file symlinks on out-of-source builds

[Michael Jackson]

I'll throw a "no" vote on that but what I would like to hear is some  
more detail from Rodolfo explaining why he thinks he needs this? Have  
you tried embedding the build directory inside the source directory?  
Some of us use this type of setup and it seems to work really nicely  
with IDEs, Text Editors, and the terminal?
