dlfcn-win32 [](https://ci.appveyor.com/project/dlfcn-win32/dlfcn-win32/branch/master)
===========
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:

Using This Library
------------------
### Using CMake
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`](https://cmake.org/cmake/help/latest/variable/CMAKE_DL_LIBS.html)
(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})
...
~~~
