That sounds fine to me.

For my FreeEOS project I developed FindBLAS.cmake and FindLapack.cmake and a
helper file called CheckFortranFunctionExists.cmake to deal with the issue
of finding BLAS and LAPACK on my Linux platform. However, my solution
didn't deal with other platforms very well because I didn't have the
required platform-dependent BLAS and LAPACK expertise. Fortunately, though,
Alin Elena was much more in the know about these issues so he took over my
efforts and vastly improved them. I understand the result works well on the
Mac now since he is particularly interested in that platform. To see his
latest version, look for the above files in
http://www.cmake.org/cgi-bin/viewcvs.cgi/Modules/?root=CMake.
I am completely tied up with something else for the next month or so.
Therefore, Jerry, if you are anxious for a quick solution you will have to
learn how to use those files for yourself. The basic procedure would be the
following:
(1) Copy the above files to cmake/modules so that PLplot can access them
since we use CMake 2.4.x at the moment rather than the cvs version of CMake.
(2) Change ada.cmake in cmake/modules to extract library locations from
those files into CMake variables LAPACK_LINKER_FLAGS and LAPACK_LIBRARIES.
Follow the last few lines of free_eos.cmake (which can be found at
http://freeeos.svn.sourceforge.net/viewvc/freeeos/trunk/cmake/modules/free_eos.cmake?view=log).
These first two steps should be completely straightforward, and the two
message lines you copy from free_eos.cmake will tell you the resulting
values of LAPACK_LINKER_FLAGS and LAPACK_LIBRARIES, i.e., will tell you if
CMake found everything properly on your Mac OS X platform If there is any
problem with that, then you may need to modify the three files
appropriately, but I suspect everything will be fine.
(3) Change our Ada library link code (and possible examples as well?)
to use LAPACK_LINKER_FLAGS and LAPACK_LIBRARIES appropriately.
This step will require a good overview of our build system (so you know
where our Ada library and examples are built and with what commands) and
will probably require some experimentation to get right.
Jerry, good luck with this! Although I am pretty busy at the moment, I am
always available to answer a quick question if you run into any roadblocks
with the above.
