We are intentionally hard coding to be using v66 ISA here?

Yes... We'd have to add yet another Hexagon-related user variable to the cmake configuration that specifies the Hexagon architecture to make it flexible. Are you concerned about the hard-coding, or about the specific version used?

Mainly the hard-coding. Wondering if we can expose this to the top-level config.cmake for instance:

I can add USE_HEXAGON_ARCH variable to config.cmake. Should have another patch ready soon.

Can you switch this to target_include_directories? You may have to call it multiple times with different targets (tvm_objs, tvm). I know the old code used include_directories, but it would be good to clean this up.

I think that would also require moving the include(cmake/modules/Hexagon.cmake) to be after the definitions of tvm_objs. It would then also require using the target_sources function instead of appending to the RUNTIME_SRCS variable, since the RUNTIME_SRCS variable isn't used after the definition of the object libraries.

If we're cleaning up the module usage, I'd lean toward having every module define an object library, along with any flags that are needed. It looks like there's a nice new feature in cmake 3.12 that allows object libraries to specify linkage. There are some workarounds for earlier versions, including using static libraries, but needing the -Wl,--whole-archive flag is causing some issues.

I think I'd stick with the current style for consistency with other modules, but I want to change it to use object libraries if/when we require a newer version of cmake.

These targets are created after the target-specific modules are included. In other words, they don't yet exist here.

Edit: This is essentially what @Lunderberg said, I didn't see his comment when I was replying.

I would like to clean up the module, but I don't want to put too much of a burden on you @kparzysz-quic. If its too much work switch this to target_include_directories, we can leave it as further work.

@Lunderberg I think cmake 3.9 is the minimum version of cmake we support. There are a lot of useful features in 3.12 and 3.13 that I'd like to use, but many OSs don't have newer version of cmake.

That was my guess, since ubuntu18.04 is on 3.10 in the repo. It would be nice to have a newer version, but not worth dropping support. It looks like the CMakeLists.txt declares a minimum version of cmake 3.2, while the documentation gives 3.5.

Can you also switch this to target_include_directories?
