Been having this issue for a while with building SMTK against MOAB. We are using MOAB 4.9.0

```auto
/opt/dev/cmb-6.0.0-9d95e0c07b6802176294760e36a4ec53043f70a4/thirdparty/smtk/smtk/mesh/moab/HandleRange.h:20:33: fatal error: moab/EntityHandle.hpp: No such file or directory
compilation terminated.
thirdparty/smtk/smtk/CMakeFiles/smtkCore.dir/build.make:1118: recipe for target 'thirdparty/smtk/smtk/CMakeFiles/smtkCore.dir/attribute/json/jsonHelperFunction.cxx.o' failed
make[2]: *** [thirdparty/smtk/smtk/CMakeFiles/smtkCore.dir/attribute/json/jsonHelperFunction.cxx.o] Error 1

```

Here is the patch I created to fix the issue:

Thanks Corey! I will try this patch out [just now](https://gitlab.kitware.com/cmb/smtk/merge_requests/1235).

We are happy taking patch fixes for SMTK/CMB; additionally, we encourage the submission of merge requests to the [SMTK](https://gitlab.kitware.com/cmb/smtk) and [CMB](https://gitlab.kitware.com/cmb/cmb) repositories directly. The more external contributors, the better!

It would be better to use `target_include_directories` for moab (on the smtkCore target) than to use `include_directories`, which blindly adds moab include dirs to every target.

Sorry for the delay. I have implemented David’s suggestion [here](https://gitlab.kitware.com/cmb/smtk/merge_requests/1273). Corey, would you mind testing this to see if it solves your issue?
