Error: ld.exe: cannot find -lssl -lcrypto

Question

I am trying to run the code from this Website: https://quuxplusone.github.io/blog/2020/01/26/openssl-part-3/ but i get the following error message

C:/Strawberry/c/bin/../lib/gcc/x86_64-w64-mingw32/8.3.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lssl -lcrypto
collect2.exe: error: ld returned 1 exit status

I dont know what is the problem, since when i use

gcc -o client clientserv.cpp -lssl -lcrypto

to Compile other code it works fine but using the command from the website doesnt work.

Edit: The command used on the website is

g++ -std=c++14 clientserv.cpp $(pkg-config --cflags --libs openssl) -o https-server

This command requires OpenSSL development libraries. Did you install the correct package for your Linux distribution? — Sam Varshavchik, Aug 22 '22 at 13:36
Does `g++ -std=c++14 clientserv.cpp -lssl -lcrypto -o https-server` work? — jabaa, Aug 22 '22 at 13:50

It seems like people ignore that `gcc -o client clientserv.cpp -lssl -lcrypto` _"works fine"_. That would mean that the libraries are correctly installed. — jabaa, Aug 22 '22 at 13:55
@SamVarshavchik I installed the correct Version of OPENSSL on my windows machine — oneandonlyk, Aug 23 '22 at 05:26
@jabaa No, then i get alot of errors that there are undefined reference to 'std::allocator::allocator()' for example — oneandonlyk, Aug 23 '22 at 05:30
Cannot reproduce, `g++ test.cpp $(pkg-config --cflags --libs openssl) -o test` works just fine. The error message `cannot find -lssl -lcrypto` suggests that something is wrong with pkg-config. Normally each library that is not found is listed on its own line. Since the two are packed together in your case, it looks like there is some kind of invisible character between them that is NOT the ordinary ASCII space. — n. m. could be an AI, Aug 23 '22 at 06:34

So it seems that the proper command to run it on windows is

g++ -std=c++14 clientserv.cpp -lssl -lcrypto -o https-server

When using gcc instead it has some Problems, which led me to believe i have some configuration problem
