cmake of cookiecutter-cppyy-cmake project fails on Windows 10

[tjorda01]

First of all thank you for creating this project. I've used cookiecutter-cppyy-cmake to create Python bindings for our C++ project successfully on Linux (Ubuntu and CentOS). I found it very easy to use and maintain the Python bindings as our C++ code evolves.

However, we now need to create Python bindings for Windows 10 deployments. Issue: After successfully running this command ...

    $ conda install -c conda-forge cookiecutter

... the cmake command fails because it can't find *.so files.

It appears that these files list *.so files instead of DLLs: FindCppyy.cmake, ROOTConfig-targets-release.cmake, and modules\RootNewMacros.cmake

I believe the following DLLs correspond to the *.so files listed in ROOTConfig-targets-release.cmake. However, I couldn't find a DLL to match the libMathCore.so:

    libCling.so    -> <my_venv home>\Lib\site-packages\cppyy_backend\bin\libCling.dll
    libThread.so   -> <my_venv home>\Lib\site-packages\cppyy_backend\bin\libThreadLegacy.dll
    libCore.so     -> <my_venv home>\Lib\site-packages\cppyy_backend\bin\libCoreLegacy.dll
    libRIO.so      -> <my_venv home>\Lib\site-packages\cppyy_backend\bin\libRIOLegacy.dll
    libMathCore.so -> ??? **Can't find a corresponding DLL for this *.so file** ???

Can you provide a version of cookiecutter-cppyy-cmake that works on Windows? If not, can you provide guidance on what steps are needed to build it on Windows? If I can't get this to work on Windows I have to scrap all the work I did using this project on Linux and find an alternate solution that works on both Linux and Windows.

Installed Software

• Microsoft Windows 10 [Version 20H2]
• Anaconda3-2021.11-Windows-x86_64.exe
• Microsoft Visual Studio 2019
• CMake 3.22.2

Detailed steps:

    (base) $ conda create --name my_venv python=3.8

    (base) $ conda activate my_venv

	NOTE: must be administrator for the following command
    (my_venv) $ conda update -n base -c defaults conda

	NOTE: running the following as adminstrator fails, so run as regular user
    (my_venv) $ pip3 install cppyy
                    ...
