h5zzfp build script fails on redhat systems using lib64 instead of lib paths

[mlohry]

Running build_conduit.sh on a red hat system is failing when it gets to searching for the zfp package previously installed.

CMake Error at CMakeLists.txt:76 (find_package):
  Could not find a package configuration file provided by "ZFP" with any of
  the following names:

    ZFPConfig.cmake
    zfp-config.cmake

On RH systems zfp is being installed with directory structure /include /bin and /lib64 instead of /lib. Symlinking lib to lib64 works around this. Or pass the zfp build -DCMAKE_INSTALL_LIBDIR=lib

Thanks for the report, I think I have a fix in build_conduit as part of PR #1495
