configure: error: Missing required libcurl - c++

Question

I'm Trying to Compile a project that's need curllib on windows xp 32-bit
i've downloaded "curl-7.35.0.tar.gz" and compiled it, copied "libcurl.m4" and "curl-config"
when i run this command in MSYS Shell:
LIBCURL="-lcurldll" ./configure CFLAGS="-O3"
It Gives me this Error:
configure: error: Missing required libcurl >= 7.15.2
i know that i hadn't installed the curl lib properly in my system that's why this error shows up
can someone tell me the right way to install libcurl in windows ? ( Note: I'm a newbie with C/C++ and compiling and all related things )
Thanks in advance !

You need to have the libcurl you downloaded/compiled in the linkers path. This means you need to take the libcurl.dll file (not the m4) and put it in the directory that the linker will search in. Usually the projects directory or one of the system libraries that are defined by default in Windows.
