I'm trying to compile a c++ project with cmake and make on OSX but it looks like make is using CXX or clang when I want to use g++ (gcc) so I can follow the answer here to tell the compiler where to find header files (#includes) for tbb used in the project: Need help getting intel TBB working?
brew list shows that I have up to date versions of cmake, make, gcc, and swig installed.
Here's the project I'm trying to compile for reference: https://github.com/nmoehrle/mvs-texturing/blob/master/README.md
