Okay, this is definately *not* a supported case.  You're asking CMake to
install a file on top of itself.  You'll have to choose a different
install location.  I usually do the following for third party software
that I build in my own prefix:

- source code in $prefix/src/project
- build tree in $prefix/src/project-build
- installation in $prefix/*

I think the fix to the bug will just be to add a check to the
CMakeLists.txt file to disallow this case.
