I don't understand this part, if not supported, then why introducing the dependency?

Currently, when building through build.py or cmake, tracing can be enabled in the build. From my understanding, this means that tracing-library (tracer.h) will get built with the #ifdef TRITON_ENABLE_TRACING sections included. Hence, when http-endpoint-library or grpc-endpoint-library include tracer.h (here and here) it will look for the tracing dependencies that tracer.h requires.

Then shouldn't tracing-library be added as http-endpoint-library / grpc-endpoint-library's dependencies?

I think this would be a good change. Currently instead of linking the tracing-library, we do something along the lines of:
http_server.h

...
#include "tracer.h"
...

and in CMakeList.txt to handle the dependencies we do:

target_include_directories(
      http-endpoint-library
      PRIVATE ${OPENTELEMETRY_CPP_INCLUDE_DIRS}
    )

But now that we are changing the tracing-library links/includes to be public, I replaced:

target_include_directories(
main/http-endpoint-library/grpc-endpoint-library
PRIVATE 
${OPENTELEMETRY_CPP_INCLUDE_DIRS})

with this:

target_link_libraries(
main/http-endpoint-library/grpc-endpoint-library
PRIVATE
tracing-library)

With assistance from @fpetrini15, I was able to verify that these changes work with the windows build as well.

Now that these libs are exposed publicly by the tracing-library that is already linked to the py-bindings target, do we need to do it again here?

Without linking and including these libraries/directories to py-bindings, the build fail which points to the src/CMakeLists.txt linking change from PRIVATE to PUBLIC not having the intended consequence. Hence, will revert the src/CMakeLists.txt level changes and keep these link/include operations.

But how can maintarget don't need handling like this? Isn't main and py-bindings conceptually the same in terms of compilation and linking?

Thank you for the suggestion. The new handling of tracing-library requires only linking py-bindings to tracing-library without including/linking any opentelemetry directories or libraries directly to py-bindings.

The fix was to link tracing-library "as is" and not link $<TARGET_OBJECTS:tracing-library> because linking the latter will not propagate the link interface of tracing-library when linked with the final library.
