Definitely add a bug report; then attach your code changes that fix it 
as a patch to the bug report.

I seem to recall this is a known issue for which clever use of variables will produce the desired result. But I would add my weight to the suggestion of a previous mailer that this is  a bug as I will now have to create different cmake implementations for windows and solaris/linux.

Mention this, too, in the same bug report. Clever use of variables 
should not be required if there is a simple/straightforward/obvious 
setting that CMake should be paying attention to... You should 
definitely be able to have one cmake implementation that works for both 
Windows and Linux.

>I couldn't see a way of getting the bootstrap script to carry out an out-of-source build or clean an existing cmake build - I need this as I have cross mounted solaris/linux drives - I made a few changes to the bootstrap script so that it builds to ./build/${cmake_system} by default. You may want to consider adding this.

The way to do an out of source build with bootstrap is to call bootstrap 
from the desired binary directory, like so (assuming source is in ~/CMake):
mac:~ david$mkdir BootStrappedCMake
mac:~ david$cd BootStrappedCMake
mac:~/BootStrappedCMake david$~/CMake/bootstrap


Hope this helps,
