I have downloaded a library and want to use in my solutions.
I have 2 directories in my library /include with all .h files and /lib with .so files.

I have added the /include directory to my projects additional include directories and now can include the .h files without compiler error. The issue is when I try to use the functionality from .h files, it gives me the link error, smth like error LNK2001: unresolved external symbol __imp__curl_easy_setopt

My guess is it doesnt see the definition of the fuinctions in .so files. (only guessing here..)

Will much appreciate if someone can help me to resolve me this issue.

msvc does not use these. The binaries you have are for likely mingw or maybe they are for a different OS. – drescherjm Apr 04 '21 at 15:16
You need to link to your .so files – Alan Birtles Apr 04 '21 at 15:17
@AlanBirtles, how? – Eduard Rostomyan Apr 04 '21 at 15:19
Hm, *.so mean shared object, so dynamic linking, but you have the tag static linking. Also you're trying to use a *.so file with the microsoft visual c++ compiler? Something seems weird. But if you are on Windows and have just a *.dll you can extract the exported symbols and generate an import library (usually *.lib) – PeterT Apr 04 '21 at 15:20
You pass the library to your compiler when you are linking, exactly how depends on your compiler and how you're building your code – Alan Birtles Apr 04 '21 at 15:20
@AlanBirtles, I use Visual Studio 2019 – Eduard Rostomyan Apr 04 '21 at 15:21
You need curl binaries produced for msvc. It will not link to .so files for mingw or gcc binaries on some other OS. – drescherjm Apr 04 '21 at 15:22
Then you need to download your library (I'm presuming libcurl) built for visual studio which will be a dll and/or a lib file – Alan Birtles Apr 04 '21 at 15:22
