Problems building the various examples

Also I am German, but OS is English. There could be some German settings for something in the OS, but I doubt anything relevant here. From what I gather this shouldn’t be a new combination in your team

As for the output. Sure, here.

CMake Warning (dev) at CMakeLists.txt:257 (IF):
  Policy CMP0054 is not set: Only interpret if() arguments as variables or
  keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  Quoted variables like "MSVC" will no longer be dereferenced when the policy
  is set to NEW.  Since the policy is not set the OLD behavior will be used.
This warning is for project developers.  Use -Wno-dev to suppress it.

C:\Optix7\OptiX_Apps>

Thanks. Me too, and yes, English OS versions.

This looks perfectly fine for an x64 MSVS 2019 command prompt and doesn’t explain at all why you could only build assimp-vc141-mt.lib/.dll versions from that at some times.

cl_version = 19.27
cl_architecture = x64

It should have always picked this generator and toolset:

  # MSVS 2019 with VC toolset 14.2
  set(GENERATOR "Visual Studio 16 2019")
  set(MSVC_TOOLSET "msvc-14.2")

The only difference between your and my system is the line

-- Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.18363.

Nothing more I can do about this.

Again thanks.

It’s working now and it doesn’t seem to problem in your scripts either. I guess the SDK is something to keep in mind in the future.
