h5* generated CMake wrappers lack options that are present in h5* wrappers generated with Autotools.

[brtnfld]

Describe the bug The CMake wrappers (h5cc, h5fc, etc.) lack the same script options as their auto tool equivalent.

Expected behavior The Autotools h5* scripts support the following options:

-c) -o) -E|-M|-MT) -l*) -prefix=*) -echo) -show) -showconfig) -shlib) -noshlib) -help, --help, -h)

Should fix #4574
