Build Failing by throwing FEMTree, PoissonRecon Issues

[medplabs]

Hi, I tried running the StandardCyborgExample as explained. Added Package Dependencies locally as suggested. However, build is failing and throwing up issues like:

FEMTree: Member reference base type 'Data *const' is not a structure or union
MarchingCubes: A template argument list is expected after a name prefixed by the template keyword
SparseMatrix: Reference to non-static member function must be called

Same, code is heavily broken

This error is coming from the PoissonRecon library. Perhaps newer versions of C++ compile this more strictly.

Unfortunately, I don’t have time to work on StandardCyborgCocoa these days, but I would welcome PRs to fix this.

I have opened a PR (#53) which includes all the necessary syntax and dependency fixes required to resolve the build errors mentioned in this issue.

The build should now run successfully.
