fatal error: 'CoreServices/CoreServices.h' file not found OS X Catalina

I am facing an above issue when running cabal install hfsevents. This is very similar to #3

Error message I get:

I have Xcode freshly installed and I am able to locate header file at /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/CoreServices.framework/Versions/A/Headers/CoreServices.h

but defining this env var (in my .zshrc) like this doesn't help

export CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/CoreServices.framework/Versions/A/Headers/"

UPD: log of cabal install with -v3 https://pastebin.com/FDygnfQB

I got there with: nix-shell -p darwin.apple_sdk.frameworks.CoreServices -p darwin.objc4.all -p darwin.apple_sdk.frameworks.Cocoa

Apologies for this being a Nix-only solution, but it should give you some idea.

Does anyone still see this problem? I've never encountered it (I get my GHC installs from GHCup usually).
