Modern CMake and xmake are on the short list.

C++11 and Vulkan are the only current planned non optional
dependencies (apart form the build tools :-)

I don't know yet whether we should have loaders within the core
VulkanSceneGraph project or outside in additional
libraries/frameworks, it's the loaders that cause the 3rd party
dependency issues.

Heh...  I just so happened that to the list of 3rd party resources
that I'm referencing this morning.

Maybe, no decisions made yet, but I'm also not polling for opinions,
the VulkanSceneGraph isn't a design by committee.

My initial code experiments have .hpp but frankly it's ugly as hell as
well as stupid - there's no header plus plus language so I'm rapidly
tiring of .hpp. Code should to be a thing of beauty not some ugly
kludge.  .h makes sense as it's a header, .cpp makes sense for source
files as it's C++.  However, public headers are placed into include
directories and that's their role, we know they are headers because
that's why we put them there, so the .h should be superfluous for
public headers and the standard C++ headers illustrate this.  If 3rd
party tools/editors can't even handle the extension less C++ standard
library headers then they aren't really up to the job.
