[CMake] No Native 64-Bit CMake Binaries?

[Eskandar Ensafi]

Hi all,

To clarify, my concern was not that a 32-bit CMake would not be able to
build a 64-bit application, nor was I worried about the performance.
Rather, considering that it is possible to build a 64-bit CMake, why is it
that the CMake website does not provide a ready built 64-bit native
binary?  I see various builds for less popular platforms such as IRIX 32
and IRIS 64, so why not 64-bit Linux and Windows versions?

Best,

Eskandar

Not sure I agree with David... :)

It is not a resource issue.  I just don't see the need?   What good is a 
64 bit CMake?   On Apple someone wanted to a 64 bit CMake, and I had 
them do bench marks, and not noticeable difference could be discerned 
between them.   So, maybe this is just a marketing thing?   We should 
make sure it is very clear that a 32 bit CMake can be used to build 64 
bit applications.  Perhaps I am missing something, but I have yet to see 
a good argument for why a 64 bit CMake would be needed for any reason.
