You should avoid this, as the symlink ends up spoofing that library's Qt4
naming convention. Better to make sure the FindQScintilla.cmake module
properly locates the name (which doesn't have any issues with finding it
here on macOS 10.11.6 using Homebrew).

Try adding libqscintilla2_qt5 to QSCINTILLA_LIBRARY_NAMES in:
https://github.com/qgis/QGIS/blob/master/cmake/FindQScintilla.cmake

and see if that helps.
