Summary:                    LIBRARY_OUTPUT_DIRECTORY for MODULE
Description: 
As per documentation for LIBRARY_OUTPUT_DIRECTORY, we have:

$ cmake --help-property LIBRARY_OUTPUT_DIRECTORY
[...]
For DLL platforms the DLL part of a shared library is
treated as a runtime target and the corresponding import library
is treated as an archive target.
[...]

And

$ cmake --help-command add_library
[...]
  ``MODULE`` libraries are plugins that
are not linked into other targets but may be loaded dynamically at runtime
using dlopen-like functionality. 
[...]

However using the following simple demo project:

$ cat foo.c
__declspec( dllexport ) int foo() { return 42; }
$ cat CMakeLists.txt
project(demo)

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/dll_part)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib_part)

add_library(foo_shared SHARED foo.c)
add_library(foo_module MODULE foo.c)


After compilation leads to:

$ find . -name \*.dll
./lib_part/foo_module.dll
./dll_part/foo_shared.dll

Which means:

1. Either MODULE is not a library since it's dll part is generated in
`LIBRARY_OUTPUT_DIRECTORY`, which imply the documentation is inaccurate

2. Or MODULE is indeed a library, but there is a bug in cmake where the dll part
of the library is generated in the `LIBRARY_OUTPUT_DIRECTORY` path.
