Hi
I had not seen a reply to your question and I thought I give my $0.02.
I'm fairly new to CMake and I've run into this problem as well.
The only solution I came up with was calling find_package(HDF5 ... *)
again if it fails the first time. On my project, I search for HDF5 using
find_package with NO_MODULE (i.e. look for a CMake generated config
file). If that fails, I assume HDF5 was not built with CMake and call
find_package(HDF5 ..) again without NO_MODULE. In this second case,
CMake searches for a FindHDF5.cmake file and executes it. I believe that
FindXXX.cmake modules are designed for projects/packages that are not
built with CMake. By the time FindXXX.cmake is invoked the find_package
call is already in a Module search mode and has eliminated the
possibility that a CMake config file exists.

Hi! I'm working on some classes for ITK4 that use the HDF library, and

If you build & install HDF5 with CMake, you MUST use
find_package(HDF5 [REQUIRED] NO_MODULE)
in order to use HDF5. If you use the more natural command
find_package(HDF5 [REQUIRED])
then the cmake/share/cmake-2.8/Modules/FindHDF5.cmake fails to find
the installation.
The FindHDF5.cmake depends on HDF5 using the autoconf-based build
system, and searches for one of the HDF utilities to run.
This doesn't feel like a good situation. Shouldn't the FindHDF5.cmake
perhaps look for both sorts of HDF5 installs?
