Windows pthreads library misspelling

[Logitude]

In cmake/Modules/FindPThreads_windows.cmake the pthreads library is misspelled as "pthreadsVC2". It should be "pthreadVC2".

@Logitude Hi,

It looks like it was renamed 3 days ago: https://github.com/Microsoft/vcpkg/commit/fd2330af7af3c8b523bec5e3de8fdbaf7ed75f5e

Do you get an error during compiling?

[Logitude]

I did get an error during the cmake checks:

-- Could NOT find PTHREADS (missing: PTHREADS_LIBRARY)
-- Found OpenMP_C: -openmp (found version "2.0")
-- Found OpenMP_CXX: -openmp (found version "2.0")
-- Found OpenMP: TRUE (found version "2.0")
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
PTHREADS_LIBRARY (ADVANCED)

I was able to build after making the following change:

diff --git a/cmake/Modules/FindPThreads_windows.cmake b/cmake/Modules/FindPThreads_windows.cmake
index 2b7d76a..6ecfd3e 100644
