[CMake] FindHDF5.cmake configuration -- finds regular, can't find HL

[Tim Gallagher]

I reported this awhile back: 

http://public.kitware.com/Bug/view.php?id=12316 

The patch I attached would work, but it fails in some select cases so it wasn't put in. I don't remember the details, it may fail when there is no HL or something. But you can try it and see if it works for your case.

Hi all, 
I am supporting cmake version 2.6. I have included the latest FindHDF5.cmake file I could find in my distro … except for one dependency that needed to be added, this seems to work fine. 

When I try to find_package(HDF5 COMPONENTS … ) it works for the C (and Fortran) component but not for the HL library or Fortran_HL. Here is the output for the C language HL variant: 
-- Found HDF5: HDF5_hdf5_hl_LIBRARY_RELEASE-NOTFOUND;/usr/local/dms/pkg/hdf5/1.8.7-intel12.0-parallel/lib/libhdf5.a;/usr/lib64/libz.so;/usr/lib64/libm.so 

Could it be cmake is looking for the unadorned libhdf5.a for the regular library and libhdf5-release or something like that for the hl library. Why the difference? If so is this a type of behavior that can be switched off? 

Here are the contents of the directory, in case the issue of the HL libraries not being there comes up: 
$ ls /usr/local/dms/pkg/hdf5/1.8.7-intel12.0-parallel/lib 
libhdf5.a libhdf5_hl.a libhdf5_hl.la 
libhdf5_fortran.a libhdf5hl_fortran.a libhdf5.la 
libhdf5_fortran.la libhdf5hl_fortran.la libhdf5.settings 

Thanks for any insight. I realize numerous patches have been made to FindHDF5.cmake, and that I might be voiding my warranty by backwards porting it, but it sure seems like it should work for all the components if it works for two of them.
