Hmm. I had never heard of CMAKE_FIND_ROOT_PATH until now, but it
certainly wasn't around when I learned all about CMAKE_LIBRARY_PATH
and CMAKE_INCLUDE_PATH years ago.  I guess the problem is I have too
long a history with CMake, and I haven't been paying enough attention to
the more recently developed features.  :-)

I tried the cmake option
-DCMAKE_FIND_ROOT_PATH:PATH=/home/software/lapack/install_double
with both cmake-2.8.5 and cmake-2.8.7-rc2 and got the same results
as before: the desired consistent lapack/blas libraries for 2.8.5, i.e.
-- LAPACK_LIBRARIES =
/home/software/lapack/install_double/lib/liblapack.a;/home/software/lapack/install_double/lib/libblas.a

and an inconsistent mixture of libraries for rc2, i.e.,

-- LAPACK_LIBRARIES =
/home/software/lapack/install_double/lib/liblapack.a;/usr/lib/libf77blas.so.3gf;/usr/lib/libatlas.so.3gf

The above two results were obtained both with and without CMAKE_LIBRARY_PATH
set.

So it appears this is a second regression for the rc2 version of the
lapack/blas find modules compared to 2.8.5; CMAKE_FIND_ROOT_PATH is
partially ignored.

I hope Dave draws the right conclusion here.  :-)
