[svn-r9100] Purpose:
Bug fix

Description:
The examples would compile even if some header file were not
installed.  That was because the CPPFLAGS has -I... components
that included the src directories.

Solution:
The h5cc or h5pcc commands should have all the necessarily
library include directories covered.  Changed CPPFLAGS to
search only the examples source directory for local header
files.

Platforms tested:
No h5committest tests which do not check examples.
Hand tested it in sol.
