ENVIRONMENT
macOS Sonoma (14.4.1)
Xcode 15.3
NS 8.7.0
@nativescript/ios 8.7.1
@nativescript/canvas 2.0.0-beta.21
@nativescript/canvas-three 2.0.0-beta.21

PROBLEM
In "App_Resources/iOS/build.xcconfig" I set HEADER_SEARCH_PATHS (including $(inherited)), which is necessary for my native code. @nativescript/canvas also sets HEADER_SEARCH_PATHS (including $(inherited)) in "node_modules/@nativescript/canvas/platforms/ios/build.xcconfig". I'm guessing this is what causes the problem...

fatal error: 
      'include_path/some_header.hpp' file not found

My native code longer compiles until I manually add headers search paths in Xcode. Setting HEADER_SEARCH_PATHS in "App_Resources/iOS/build.xcconfig" no longer works.
