• NVIDIA Kepler generation or later GPU
• CUDA Toolkit 6.5 or later (Toolkit 10.2 recommended)
• Visual Studio 16 2019 or later
• CMake 3.10 or later

Tested on CUDA Toolkit 10.2 & Visual Studio 16 2019 only. Other versions may not work properly.

1. Move to GVDB_Library Directory
2. Generate files using CMake (Put your CUDA Path at argument)

cmake -B ./build -G "Visual Studio 16 2019" -DCUDA_PATH_BUILD="YOUR_CUDA_PATH"

# Example
cmake -B ./build -G "Visual Studio 16 2019" -DCUDA_PATH_BUILD="C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v10.2"

3. Open build/gvdb.sln
4. Set Output Directory of gvdb project as GVDB_Library/lib path (ex. $(SolutionDir)..\lib)
5. Set Target Extension of gvdb proejct as Static Library (*.lib)
6. Set Target File Extension of gvdb project as .lib
7. Build gvdb project with 'Release' (It will generate gvdb.lib at GVDB_Library/lib)

1. Generate Visual Studio project files (using UE_GVDB.uproject)
2. Open UE_GVDB.sln
3. Build and Launch
