stack build fails, hspec missing dependency libtinfo

[VillePuuska]

Running stack build in Ubuntu 22.04 inside WSL2 (in Win 10) failed with an error along the lines of (forgot to copy the actual error before closing the terminal):

hspec-core                 > error: cannot find -ltinfo
hspec-core                 > error: ld returned 1 exit status
hspec-core                 > failed in phase `Linker'. (Exit code: 1)

Fixed by installing libtinfo

sudo apt install libtinfo-dev

Maybe worth adding to list of common problems.

On Fedora I needed to run

dnf install ncurses-devel

when I encountered this issue.
