If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is. If the header file does exist, it may contain errors that are caught by the C compiler at the preprocessing stage. In this case you can re-run configure with the verbosity flag -v3 to see the error messages. cabal: Leaving directory '/tmp/cabal-tmp-20213/bindings-libzip-1.0.1' Failed to install bindings-libzip-1.0.1 cabal: Error: some packages failed to install: bindings-libzip-1.0.1 failed during the configure step.
