It seems that the linker is looking for the curl library. Before you
can write curl programs, you have to compile curl itself so the
libcurl library is available for curl programs to link with. Or make
the library available to the program, for example if you have the
libcurl library as a binary that came with another program in MinGW or
Cygwin for example.
