I am also getting errors that are similar

you can find LIBUSB library here libusb-win32. or what you need is libnfc-1.8.0, I published a win32 release, you can find in my fork project here

Hi,

Under 64-bit Windows, this problem should be fixed by changing NAMES and PATHS values at this line in "libnfc\cmake\modules\FindLIBUSB.cmake" :

FIND_LIBRARY(LIBUSB_LIBRARIES NAMES "libusb" PATHS "$ENV{ProgramFiles}/LibUSB-Win32/lib/msvc_x64")

Because there is a file named "libusb0.dll" (with a zero at the end) in "LibUSB-Win32\bin\amd64" but there is no zero at the end of "libusb.lib" in "LibUSB-Win32\lib\msvc_x64".

I also tried to add others path as "$ENV{ProgramFiles}/LibUSB-Win32/lib/msvc_i64" ... in PATHS, for example : FIND_LIBRARY(LIBUSB_LIBRARIES NAMES "libusb" PATHS "$ENV{ProgramFiles}/LibUSB-Win32/lib/msvc_x64" "$ENV{ProgramFiles}/LibUSB-Win32/lib/msvc_i64") but the "right" choice is not guaranteed because depend of order.

I also tried to add more choices in NAMES as : NAMES "libusb" "libusb0" is it usefull/risky for future versions ?

I also tried to add PATH_SUFFIXES and change PATHS : PATH_SUFFIXES bcc dynamic gcc msvc msvc_i64 msvc_x64 PATHS "$ENV{ProgramFiles}/LibUSB-Win32/lib but bcc was chosen and i use msvc_x64.

I dont know if NO_DEFAULT_PATH is usefull in this case, but maybe you can influence FIND_LIBRARY() by setting CMAKE_LIBRARY_ARCHITECTURE with the good value at runtime as indicated in https://cmake.org/cmake/help/latest/command/find_library.html.

Hope that will help.
