I tried to build the thunderSVM with VS 2019 and Cuda 10.2, but the build has failed with below error - Command to get the solution file- cmake .. -DCMAKE_WINDOWS_EXPORT_ALL_SYMBOLS=TRUE -DBUILD_SHARED_LIBS=TRUE -DBUILD_TESTS=OFF -DUSE_CUDA=ON -G "Visual Studio 16 2019" when I try to build the thundersvm solution , it results in below error 2>C:/thundersvm/src/thundersvm/kernel/kernelmatrix_kernel.cu(12): fatal error C1083: Cannot open include file: 'cub/cub.cuh': No such file or directory

If I include path of cub directory in CMake file - include_directories(“C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.2/include/thrust/system/cuda/detail”) it resulted in a lot of undefined symbol errors.
