Spent an entire day attemting to compile and launch Unreal Engine using the custom Nvdia caustics branch here. https://github.com/NvRTX/UnrealEngine/tree/NvRTX_Caustics
The compile process takes a couple hours. I get no errors only a few similar warnings
Warning Library 'ThirdParty/Windows/DirectX/Lib/x64/dxgi.lib' was not resolvable to a file when used in Module 'DX11', assuming it is a filename and will search library paths for it. This is slow and dependency checking will not work for it. Please update reference to be fully qualified alternatively use PublicSystemLibraryPaths if you do intended to use this slow path to suppress this warning.
And then when trying to launch an instance of UE4 from within VisualStudio2017 I get the following error several times (which is obviously related to the warning)
cannot open input file 'ThirdParty\Windows\DirectX\Lib\x64\dxgi.lib
Have googled for hours but cannot seem to find a solution. Can any CPP experts help?
