[CMake] Nested While Loops

[Mike Jackson]

Does cmake support nested while loops? I have a quadruple nested while  
loop and it looks as though only the inner most loop is being executed  
once.

HEre is a CMakeLists.txt file that illustrates the problem:

I tried this on CMake 2.6.1 and CMake CVS HEAD.. Any help would be  
appreciated. I am trying to generate a folder hierarchy in preparation  
for some cross platform tests.. other wise I would just use a shell  
script.
