used MSYS2 terminal

Inatalled required packages
pacman -S -q --noconfirm mingw64/mingw-w64-x86_64-pkg-config mingw64/mingw-w64-x86_64-gobject-introspection mingw64/mingw-w64-x86_64-gtksourceview3 mingw64/mingw-w64-x86_64-webkitgtk3

restarted machine

optional Emacs configuration

installed Emacs

In MSYS2 terminal I ran
pacman -S mingw64/mingw-w64-x86_64-emacs

created emacslauncher.bat

In MSYS2 terminal I ran
cd c:/Users/IEuser
touch ./emacslauncher.bat
emacs ./emacslauncher.bat

In the editor I have pasted the following
set PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH%

set XDG_DATA_DIRS=c:/msys64/mingw64/share
set PKG_CONFIG_PATH=c:/msys64/mingw64/lib/pkgconfig
set HASKELL_GI_GIR_SEARCH_PATH=c:/msys64/mingw64/share/gir-1.0

saved the file and quit Emacs.
used emacslauncher.bat

Now I clicked on the circle next to Windows start button and searched for
  emacslauncher.
That has started Emacs editor. I have pressed “Alt+x” keyboard shortcut and
  typed eshell and pressed Enter. That gave me a shell that is in my opinion
  more comfortable than MSYS2 shell.
I typed some commands.

tried cabal

eshell

In eshell I typed
c:/Users/IEUser $ cabal --help
cabal: command not found

In Powershell and cmd cabal has worked. So I decided to modify the way I launch
  Emacs.
set PATH=C:\msys64\mingw64\bin;C:\msys64\usr\bin;%PATH%
set XDG_DATA_DIRS=c:/msys64/mingw64/share
set PKG_CONFIG_PATH=c:/msys64/mingw64/lib/pkgconfig
set HASKELL_GI_GIR_SEARCH_PATH=c:/msys64/mingw64/share/gir-1.0

C:\msys64\mingw64\bin\runemacs

and closed Emacs and started it again pressing left Windows button and searching
  for enacslaunche.bat. After that my $PATH looked OK, I had nice Unix shell in
  Emacs and cabal worked.
modified cabal configuration

The command cabal user-config int gave me the location of cabal file. So I
  modified the extra-*-dirs to point to msys libraries.
-- flags:
extra-include-dirs: c:/msys64/mingw64/include
-- deterministic:
-- cid:
extra-lib-dirs: c:/msys64/mingw64/lib
-- extra-framework-dirs:
extra-prog-path: C:\Users\IEUser\AppData\Roaming\cabal\bin
-- instantiate-with:

tried cabal again

cabal update
cabal install gi-gtk

And got the error
Warning: The package has an extraneous version range for a dependency on an
internal library: pretty-show ==1.6.13. This version range includes the
current package but isn't needed as the current package's library will always
be used.
cabal.exe: The program 'happy' is required but it could not be found.

cabal.exe: Error: some packages failed to install:

cabal install alex
cabal install happy
cabal install gi-gtk

so far so good
