Could NOT find CURL (missing: CURL_LIBRARY CURL_INCLUDE_DIR)

OTLP_HTTP needs the CURL library, CURL needs to be installed first.

[Odinaka-git]

oh, thank you. Also after I download, the libraries, how do I link them all together.

[Odinaka-git]

In a way that cmake will be able to find the library

The otel-cpp cmake script will locate it automatically if it is installed in the default windows search path.
