Building issue with architecture x86_64

[VirgileF]

Hey! DeepSDF looks very nice but I'd like the reproduce the code and I am struggling in compiling the mesh preprocessing routines.

Here are some info on my system (macOS X Monterey 12.0.1):
ProductName: macOS
ProductVersion: 12.0.1
BuildVersion: 21A559
Darwin MacBookPro 21.1.0 Darwin Kernel Version 21.1.0: Wed Oct 13 17:33:23 PDT 2021; root:xnu-8019.41.5~1/RELEASE_X86_64 x86_64

Here are the steps I followed:

1. dependencies:

• brew install cli11
• brew install nanoflann
• brew install eigen
• git clone Pangolin repo and install it using following method: Build Issue #81 (comment)
• brew install glfw (turns out to be necessary for Pangolin to build properly)

2. deepsdf

• git clone deepsdf repo
• mkdir build && cd build
• cmake .. -DCMAKE_CXX_STANDARD=17

But then when I run make -j, I am getting the following error:

It seems like it is related to some Undefined symbols for architecture x86_64 (third line of the aforementioned error traceback).
Have you guys ever seen this error come up? Do you have any clew how to troubleshoot it further?

Thanks in advance for your help! :D
