I am trying to use the libcurl library, and did all the necessary things I could think of:
In the properties:
(C/C++>General) Additional Include Directories: "C:\Program Files\cURL\include\curl" (header files can be found here)
(Linker>General) Additional Library Directories: "C:\Program Files\cURL\lib"
(Linker>Input) Additional Dependencies: "C:\Program Files\cURL\lib\libcurl.lib"
DLLs are put in system32, and finally I included curl.h.
However, it still gives me unresolved externals. The functions I use, are recognized by VS though. The object type 'CURL' and 'CURLcode' are recognized.
