Build fails on M1 Mac | Cannot find OpenMP

[FreakTheMighty]

Describe the bug

The build fails when attempting to build on an M1 mac when it fails to find OpenMP Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)

To Reproduce

• On an M1 mac running Mac os 14.4
• Install Mac dependencies according to these instructions
• Install common dependencies using these instructions

Finally, when running

git clone --recursive https://github.com/stella-cv/stella_vslam.git
cd stella_vslam
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
make -j4
sudo make install

I get this output and error

make -j4
sudo make install

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.


CMake Deprecation Warning at CMakeLists.txt:14 (cmake_policy):
  The OLD behavior for policy CMP0074 will be removed from a future version

  The cmake-policies(7) manual explains that the OLD behaviors of all

  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.
