Subject: [PATCH] FindHDF5: Fix Windows compile-line parsing

We modify the signature of _HDF5_parse_compile_line to pass the command
line variable name rather than the command line itself.  Otherwise the
CMake language MACRO implementation tries to parse the command line as
CMake syntax, which does not like backslashes.
