node-gyp fails: 'framework not found DeckLinkAPI' on Mac

[florisporro]

Somehow I'm unable to install macadam on Mac. All prerequisites are met, I tried on two different machines one running Mojave (10.14.6) and the other running Catalina (10.15.2).

Xcode is installed on both machines. Command line tools as well.

The Mojave machine is running:

• Blackmagic Desktop Video v10.11.2
• xcode v10.2.1
• node v12.14.1
• node-gyp v3.8.0
• Python v2.7.10

The Catalina machine is running

• Blackmagic Desktop Video v11.4.1 (latest)
• xcode v11.3.1
• node-gyp v5.0.5
• node v12.14.1
• Python v2.7.16

In the case of Catalina, I ran through the node-gyp Catalina debug steps and passed the acid test:
https://github.com/nodejs/node-gyp/blob/master/macOS_Catalina.md

This is the console output on the Catalina machine when attempting to install with Yarn:

error /Users/.../elecular/node_modules/macadam: Command failed.

Output is similar on the Mojave machine.

ld: framework not found DeckLinkAPI is very similar to #6, however the debugging steps with xcode command line tools that worked there have not helped in my case. Thinking this might be related to a change in the Blackmagic API?

Tested, this is fixed by #20 (comment)
