To add libserialport support to Windows MSVC build

[mcuee]

As of now, Windows MSVC build does not support libserialport.

It will be good to add the support of libserialport for the Windows MSVC build.

One approach is to create a fork avrdude-libserialport under the avrdude organization. Change it for Windows and CMake, and then integrated it into MSVC build, same as the approach developed by @mariusgreuel.

Known Windows specific issues.

Bug

• avrdude MSVC build problem with USB composite device (avrdude-libusb library issue) -- low priority #968 (MSVC build only)
• Unable to build libavrdude dynamic library under Windows and macOS #1414

Lack of features compared to Linux and macOS
MSVC build

• To add libserialport support to Windows MSVC build #1552
• CH341A futher improvement -- to support MSVC build #1440
• ftdi_syncbb: very slow D2XX based MSVC build compared to libftdi based MinGW build #1253 (works but slow speed)

MinGW build

• To adopt PR #1264 approach of using Readline replacement for MinGW build (Low Priority) #1271

Just wondering if you can help to fork the following repo under the avrdudes organization. I do not have the permission to do that.
https://github.com/sigrokproject/libserialport

The idea is to add CMake files to libserialport fork and then try to integrate that into avrdude MSVC build.

@MCUdude

Thanks. Can you add me as a collaborator to the repo? I do not have the access to that repo now.

To do:

1. improve https://github.com/avrdudes/libserialport
2. to make it compatible with MSVC
3. adding CMake build script
4. integrate into avrdude MSVC build

No 2 and No 3 may require quite some efforts.

Remove this from avrdude 7.4 milestone since there is no active development on this topic.
