Compilation error

[ajikmr]

Hello,
I am trying to compile PVTPackage in standalone mode (i.e. not as a submodule in GEOSX simulator). I get errors for std::make_unique. I fixed that by setting cxx compiler version to 14 in CMake files.

Next, examples are giving error. I am able to compile PVTPackage lib file upon commenting out "add_subdirectory(examples)". Could you please take a look. Or add compilation instructions to the package.

System info: Ubuntu 20.04 lts / gcc9.4.0

Thanks.
