dlfcn-win32 is an implementation of dlfcn for Windows.
dlfcn is a set of functions that allows runtime dynamic library loading. It is standardized in the POSIX. Windows also provide similar routines, but not in a POSIX-compatible way. This library attempts to implement a wrapper around the Windows functions to make programs written for POSIX that use dlfcn work in Windows without any modifications.
It follows the standard as described here:

Once the library has been installed, add to your project CMakeLists.txt :
...
find_package(dlfcn-win32 REQUIRED)
...
target_link_libraries(<target> dlfcn-win32::dl)
...
If you want to use this library in a cross-platform project, a convenient way
to proceed is to define the CMake variable CMAKE_DL_LIBS
(that is normally empty on Windows) and then use it for linking:
...
if (WIN32)
find_package(dlfcn-win32 REQUIRED)
set(CMAKE_DL_LIBS dlfcn-win32::dl)
endif ()
...
target_link_libraries(<target> ${CMAKE_DL_LIBS})
...
This library uses the Process Status API in Windows (psapi.lib). If you are
linking to the static dl.lib or libdl.a, then you would need to explicitly
add psapi.lib or -lpsapi to your linking command, depending on if MinGW is
used.
