Description of issue

When running brew install opencv it ends up installed in directory/opt/homebrew/Cellar/opencv/4.9.0_8.reinstall

Consequently I get linker errors as it appears that the .reinstall suffix is ignored in any linker flags, specifically this was the case for a golang GOCV example program with CGO_LDFLAGS set:

export CGO_LDFLAGS="-L/opt/homebrew/Cellar/opencv/4.9.0_8.reinstall/lib -lopencv_stitching -lopencv_superres [+ all other libs]

Linker error: (note no .reinstall suffix in path)
Linker error dyld[32984]: Library not loaded: @rpath/libopencv_xfeatures2d.409.dylib ... Reason: tried: '/opt/homebrew/Cellar/opencv/4.9.0_8/lib/libopencv_xfeatures2d.409.dylib' (no such file)

A secondary problem is that pkg-config paths end up being incorrect .

Tried brew link, brew update with no difference. In the end I made a temp hack by adding a symlink 4.9.0_8 ⇒ /opt/homebrew/Cellar/opencv/4.9.0_8.reinstall in /opt/homebrew/Cellar/opencv/ but this doesn't seem right.

Can anyone help me understand what is going on here?
