For Fedora EPEL we often end up packaging newer versions of cmake as cmakeXY

for this. Is there any interest in cmake itself for supporting this kind of
thing?
Not particularly. That does look pretty invasive.
Why not just install it to /usr/lib/cmake34 with normal names and symlink
the versioned names? E.g.
/usr/bin/cmake34 -> /usr/lib/cmake34/bin/cmake
/usr/bin/ctest34 -> /usr/lib/cmake34/bin/ctest
...
I have many different CMake versions installed on my system in different
directories and use aliases or symlinks to reference them without being
in my PATH directly.

I'm not sure this would work. There seems to be many places in the code
(some of which the patch addresses) where it calls executes "cmake" or
"ctest" regardless of the name it was called with. If
/usr/lib/cmake34/bin was not in the path (which would be the case with
our EPEL packages unless we did more configuration) it would then end up
calling the system cmake/ctest/etc. This sounds like a recipe for
disaster. Or does cmake/ctest modify PATH internally?
