This is something missing from your (unstated) Linux installation.
curl-config is part of the original libcurl sources, but Linux
distributors tend to separte it out. *How* they do so is
non-standard:
Fedora and other RPM-based distributions tend to use libcurl-devel
Debian and related tend to use libcurl-dev
You need to figure this out for your distribution and install the
missing piece.
