HDF5 Build Fails to Incorporate Zlib and and SZIP

[mkitti]

Description / Steps to reproduce the issue

Here is a test program test_filters.c:

#include "hdf5.h"
#include <stdio.h>

int main() {
        H5open();
        printf("H5Z DEFLATE filter: %d\n", H5Zfilter_avail(1));
        printf("H5Z SZIP filter: %d\n", H5Zfilter_avail(4));
        return 0;
}

Compiling this with gcc test_filters.c -lhdf5 -o test_filters and running test_filters results in the following output:

$ ./test_filters
H5Z DEFLATE filter: 1
H5Z SZIP filter: 0

Running make-pkg gives the following output:

CMake Warning at CMakeFilters.cmake:147 (find_package):
  By not providing "FindSZIP.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "SZIP", but
  CMake did not find one.

  Could not find a package configuration file provided by "SZIP" with any of
  the following names:

    SZIPConfig.cmake
    szip-config.cmake

  Add the installation prefix of "SZIP" to CMAKE_PREFIX_PATH or set
  "SZIP_DIR" to a directory containing one of the above files.  If "SZIP"
  provides a separate development package or SDK, be sure it has been
  installed.

Expected behavior

$ ./test_filters
H5Z DEFLATE filter: 1
H5Z SZIP filter: 1

Actual behavior

$ ./test_filters
H5Z DEFLATE filter: 1
H5Z SZIP filter: 0

My guess is that we have to either define ZLIB_DIR and libaec_DIR. Alternatively, we could create a FindSZIP.cmake and Findlibaec.cmake
