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.
