unable to build using macOS 26 beta

[coffnix]

Environment:

• OS: macOS 26.0 beta Xcode 26.0 Build version 17A5241e
• qView version: qView-7.0-rc1

The removal of AGL from the qView 7.0-rc1 Makefile is necessary because Apple deprecated the AGL framework in macOS Sequoia (15.0) and removed it from the macOS 26.0 SDK with Xcode 26, causing the ld: framework 'AGL' not found error during compilation; see Apple Developer Documentation for details.

Xcode 26 dropped AGL which has broke qview. See my patch:

This is a QT old shit, created by qmake. To see this, run: grep -i '-framework\ AGL' /opt/homebrew/Cellar/qt/ -r

macOS Tahoe 26 Beta 2 Release Notes:

AGL

Deprecations

AGL is no longer available in the macOS SDK. AGL was previously used to present OpenGL content in Carbon apps, and Carbon no longer exists in the SDK. AGL symbols now do nothing on 64-bit systems, including Intel x86_64 and Apple Silicon Macs. It is safe to remove any AGL usage and stop linking AGL. OpenGL still remains in the SDK. (153913819)
