calling external service from Apache Web Server Module

I am writing a Apache web server module where I am inspecting the various incoming requests and based on various parameters, sending a report to external (REST)service. Based on the response from the service I may allow/block/redirect the current request. I am already using libcurl to consume the external service, but here I need to add a dependency on external library(i.e libcurl). I wanted to ask if there is any better way to achieve the same.
