Creating shared library using Cmake

Umer · November 13, 2024, 11:09am

Hello everyone,

I need some guidance on creating a shared library using CMake. My C++ project is already configured in Visual Studio, with the target set to generate a DLL library. I now need to create a shared library using the same C++ project.

I’ve set up most of the configuration, but I am facing a lot of errors, and I have no idea how to deal with them. Any advice or examples would be greatly appreciated.

Thanks in advance!

Thanks a lot for your reply. I checked the example in detail, but it’s not working for me. Have a great day.
