I built libcurl following the instructions for building libcurl as a static library in the curl/winbuild directory to the letter. It spat out a libcurl_a.lib, a collection of .h files, which I moved into folders that I promptly added to the PATH. I then attempt to build my program with the command
cl (*my source files*) /IC:/PATH_addon/include libcurl_a.lib Ws2_32.lib Wldap32.lib /DCURL_STATICLIB /link /LIBPATH:C:/PATH_addon/lib
Note:
I am building from the command line as the code was not written in an IDE, or on this machine
C:/PATH_addon/ is a folder where I dump all the things that need to be linked into path (it is linked to my path) so that I don't pollute the default path, or my system32 folder
However when I run the command, it tells me that there are 12 unresolved symbols:

Why can't these symbols be resolved, and is there a way to fix this?
Solution (thanks in part to the incredible @Hans Passant):
Adding the /NODEFAULTLIB:LIBCMT flag fixed the issue and allowed for a successful compile and execution.
