[petsc-dev] Trying to get the CMake instructions to work, unsuccessfully

Hi Folks,

I am attempting to use the CMake stuff that Jed put in place to build PETSc.  
I'm following the instructions currently found at

Do these need updating?  Or am I just doing something stupid?  I've run 
configure with '--with-cmake' specified appropriately, and a top-level 
CMakeLists.txt file gets created.  But when I try to run cmake with 
$PETSC_DIR/$PETSC_ARCH as my build directory, I get

rmills at ubuntu:~/proj/petsc-dev/ubuntu-gnu_g$ cmake ..
CMake Error at CMakeLists.txt:4 (include):
   include could not find load file:


-- Configuring incomplete, errors occurred!

Line 4 of the CMakeLists.txt file attempts

   include (${PETSc_BINARY_DIR}/conf/PETScConfig.cmake)

It looks like PETSc_BINARY_DIR should be $PETSC_DIR/$PETSC_ARCH, but just 
$PETSC_DIR is being used.  How is this supposed to be set?  I don't know CMake 
very well, so my apologies if this is a dumb question.
