If only libftdi is the constraint, there is an alternative solution to
replace libftdi
with libusb.

FYI -- openocd project has done quite some conversion to replace libftdi
with libusb.
Eg:
https://github.com/openocd-org/openocd/blob/master/src/jtag/drivers/mpsse.c
https://github.com/openocd-org/openocd/blob/master/src/jtag/drivers/ft232r.c

If not, I think several projects have done that to replace pthread with native
Windows thread.

Personally I think MinGW is good enough especially with distributions like
MSys 2. However, MSVC compatibility is indeed good for Windows
developers. libusb and hidapi provide compatibility and even VS solutions
files. libftdi does not fully support MSVC but it more or less works (using
CMake) if you just need to build the library (not the examples).
