This PR fixes the link with Torch when TTK is used as a library for another project such that the c++ example in TTK.
It fixes a typo
TORCH_FOUND
to@TORCH_FOUND@
.Inspired by the ZFP dependency, it sets the
Torch_DIR
variable for external projects as the value used to make TTK, in order to avoid to set this variable in external projects.It also changes the c++ version of the c++ example from 14 to 17 because 17 is needed for Torch.
