I listened to the lecture very well. I wish there was a dynamic library section in the CMake practical section. Additional) Questions Changing static to shared in add_library is not the end. In the actual code, codes for dynamically loading libraries (dlopen, LoadLibrary, etc.) must be branched and added for each platform, and additional dependencies such as CMAKE_DL_LIBS and windows.h are also needed to use that function. I am curious about how to organize platform branching while dynamically loading Shared Libraries in the runtime in the modern CMake style. If platform branching is too trivial, I think we need at least a dlopen lecture on Shared Libraries based on Linux. It is not difficult to make it work, but it is difficult to make it well, so I am curious.
