Can't build libfreenect on Windows 10/11 "LNK1120: 8 unresolved externals"

[DunZek]

I am unable to build libfreenect on Windows 10 and 11, which I believe, is due to some problems with pthreads.

Within C:\ComputerStuff\libfreenect\build, I ran and configured cmake as follows:

> cmake -L ..
  -DTHREADS_PTHREADS_WIN32_LIBRARY=C:/ComputerStuff/PTHREADS-BUILT/lib/pthreadVC3.lib 
  -DTHREADS_PTHREADS_INCLUDE_DIR=C:/ComputerStuff/PTHREADS-BUILT/include 
  -DLIBUSB_1_INCLUDE_DIR=C:/ComputerStuff/libusb-1.0.25/include/libusb-1.0 
  -DLIBUSB_1_LIBRARY=C:/ComputerStuff/libusb-1.0.25/VS2019/MS64/Debug/lib/libusb-1.0.lib
  -DBUILD_PYTHON3=ON 

Which produced this output:

Then, I tried to build with cmake --build . and produced these errors and outputs:

• Any help would be appreciated. I'm genuinely lost as to what I could be doing wrong.
• I built pthreads (got it from: http://sourceforge.net/projects/pthreads4w/) from source in C:\ComputerStuff\pthreads4w-code-v3.0.0 using nmake all install
• I'm using libusb-1.0.25 and got it as the Latest Windows Binaries from https://libusb.info/

Edit: added some hyperlinks.

I used nmake to build pthreads-4-win. I'm using Visual Studio 2019 to build with cmake.

Hi, I'm getting the same errors, but for glut, did you have any luck in fixing this? Thanks.
