So we remove that and see if things go boom?

But why does it use leftovers from before? That seems like a bug!

Clearly something is missing as that doesn't work for me:
$ cmake --version
cmake version 2.6-patch 3
$ mkdir curl-cmake
$ cd curl-cmake
$ cmake ../curl-alt/

Not exactly, that's the link phase that fails so a header file won't be used.
It is a lack of use/detect of the correct lib, librt in this case. But they
certainly seem related:
Interestingly, if I remove src/config.h and lib/config.h before I run "cmake .
&& make" it seems to work!?
BTW: how do I provide additional config options when I build with cmake? Like
"disable shared libs" and "enable debug mode" ?
