[svn-r19244] Fixes from Brad King for
1) zlib header : if custom zlib header is used from cmake project, then 
#define it so that ours is used instead of the default

2) Make install rules configurable
Add options
  HDF5_INSTALL_BIN_DIR
  HDF5_INSTALL_LIB_DIR
  HDF5_INSTALL_INCLUDE_DIR
  HDF5_INSTALL_NO_DEVELOPMENT
for configuration by a parent project.  Choose default values to
preserve prior standalone behavior.
