dd-opentracing-cpp Win x64 Error opentracing dependency missing from CMakeLists.txt - LNK2019 unresolved external symbol propagation_error_category

[buzz3791]

I’ve modified our C++ application to use DataDog. I’ve added:

1. the following include:

#include <opentracing/dynamic_load.h>

2. the DataDog include folder:

dd-opentracing-cpp\.build\vcpkg_installed\x64-windows\include

3. the DataDog link library folder:

dd-opentracing-cpp\.build\RelWithDebInfo

4. the DataDog link library: dd_opentracing.lib After the changes above, when building our C++ application with Visual Studio, the build is failing at link time with these DataDog related errors:
