dd-opentracing-cpp Win x64 - fatal error C1083: Cannot open include file: 'curl/curl.h': No such file or directory

[buzz3791]

When building dd-opentracing-cpp on Windows x64 Visual Studio C++ 2022 using the instructions at [1] I'm encountering the following error: C:\Users\first.last\dd-opentracing-cpp\src\agent_writer.h(4,10): fatal error C1083: Cannot open include file: 'curl/curl.h': No such file or directory [C:\Users\first.last\dd-opentracing-cpp\.build\dd_opentracing.vcxproj]

I installed vcpkg, cmake, and ran all previous build steps successfully including cmake -DCMAKE_TOOLCHAIN_FILE=%HOMEPATH%\vcpkg\scripts\buildsystems\vcpkg.cmake ..

But the following command is failing: cmake --build . -- -p:Configuration=RelWithDebInfo when trying to find third party include header files. Build output:

C:\Users\first.last\dd-opentracing-cpp\.build>cmake --build . -- -p:Configuration=RelWithDebInfo
