Hi Chris
Do you use https://github.com/Microsoft/vcpkg for it ? Because it is:
C++ Library Manager for Windows, Linux, and MacOS
But i'm not sure its possible to use multiple versions of same package. I
haven't found any better package manager (as well no conan).

Hi,
Try to use OSG 3.6.3 with activated GLCore on MacOSX. For example: We only have
