Re: [HTCondor-devel] Problems building htcondor on Windows

[John M Knoeller <johnkn@xxxxxxxxxxx>]

There is no interest in making the change,  the old cmake is still available and suits our needs
And we don't actually know how long it would take to find and fix all of the bugs introduced
By the change - 

And If we did switch to support the new cmake, anyone who wanted to build older versions
Of HTCondor would still have to install the older cmake. 

What we need is to have our cmake files work with either version, but at least two of us have 
tried and failed to achieve that (or gave up because of the time involved anyway).

So out of curiosity, is the dependency on CMake 2.x because of the lack of support on Linux platforms, or just lack of time to make the changeover?
