Linker cannot find the external symbols

[Joel-N99]

As the title says, the msvc linker cannot find a long list of symbols despite the library being used.

This is one of the errors:

unresolved external symbol __imp_accept referenced in function "bool __cdecl Superpowered::netAccept(int,int *,void *)" (?netAccept@Superpowered@@YA_NHPEAHPEAX@Z)

The right library, SuperpoweredWin143_Debug_MD_x64.lib , is being used as shown by the "file" column.
Apology in advance if this is a stupid mistake on my part but I can't find anything about this on the internet.
The following is the cmakelists content:

# CMakeList.txt : CMake project for console_test, include source and define
# project specific logic here.
#
cmake_minimum_required (VERSION 3.8)

# Enable Hot Reload for MSVC compilers if supported.

  cmake_policy(SET CMP0141 NEW)
  set(CMAKE_MSVC_DEBUG_INFORMATION_FORMAT "$<IF:$<AND:$<C_COMPILER_ID:MSVC>,$<CXX_COMPILER_ID:MSVC>>,$<$<CONFIG:Debug,RelWithDebInfo>:EditAndContinue>,$<$<CONFIG:Debug,RelWithDebInfo>:ProgramDatabase>>")
endif()

project ("console_test")

Hey @Joel-N99

This happens because a CMake project won't automatically link Winsock, which is used by Superpowered. With Visual Studio this is linked implicitly.

Link the Ws2_32.lib library in CMake by adding the following line somewhere after add_executable:

target_link_libraries(console_test PRIVATE Ws2_32.lib)
