試したこと

CocoaなしでのC++でのみでのhello worldなどの出力プログラムは動作確認済み
Cocoaとの相性との検索をしたもののそれらしきことを記述したサイトは見つけられませんでした

補足情報（FW/ツールのバージョンなど）

Answer 1

-lglfw-framework Cocoa

-lglfw と -framework の間に空白が必要です。

-framework IOKit-framework CoreVideo–Wno-deprecated-declarations

IOKit と -framework の間に空白が必要です。CoreVideo と -Wno-... の間に空白が必要です。
