OpenMP break error

[echen01]

Describe the bug When building the repo, cmake gives an error saying there is a break statement used with an OpenMP loop. This seems to be preventing me from compiling the source.

To Reproduce Steps to reproduce the behavior:

1. mkdir build
2. cd build && cmake .. && make

Expected behavior The code should compile.
