[CMake] RE: Cygwin cmake - Could not find CMAKE_ROOT

I have reproduced this by executing these two lines in a cygwin shell:
export PATH=/bin:$PATH
cmake --version
with cmake 2.4.7
It does not occur with cmake 2.4.3 or cmake 2.4.6
It probably occurs because cmake expects a directory structure of:
bin
doc
man
share
(There are no doc, man and share directories under "/" but they do exist in
"/usr"...)
Sounds like a cygwin-specific cmake bug... :-)
