HIPRT_ROOT_DIRECTORY never defined?

[TomClabault]

Utility::getRootDir() seems to be using HIPRT_ROOT_DIRECTORY as a mean to fix Issue #7 but HIPRT_ROOT_DIRECTORY is never defined anywhere?

I don't remember the details but my guess is that this should be defined as a compiler option. There should be an option in Cmake/Premake. You can still use the environment variable HIPRT_PATH to redefine the default path ...

[TomClabault]

I see. I couldn't find that macro defined in the CMake or Premake of HIPRT so maybe this is an omission?

[meistdan]

I think the intention was to add such an option, but we forgot. Do you need the option? I think we can modify the cmake file.

Yeah I would need that option for a project that uses HIPRT as a submodule. Without the option, the BVH building kernels always look in the parent directory of the executable and that's not ideal, this means that the BVH builders .h kernel files need to be there whereas they could all stay directly in the hiprt subdirectory
