`ghcup` will install the latest stable version of `cabal`. However, as of the time of writing this, [Input-Output](https://iohk.io) recommends using `cabal 3.6.2.0`. So, we will use `ghcup` to install and switch to the required version.

## Installing `blst`

Find out the correct `blst` version:
```bash
BLST_VERSION=$(curl https://raw.githubusercontent.com/input-output-hk/iohk-nix/master/flake.lock | jq -r '.nodes.blst.original.ref')
echo "Using blst version: ${BLST_VERSION}"
```

Download and install `blst` so that `cardano-base` can pick it up (assuming that `pkg-config` is installed):
```bash
: ${BLST_VERSION:='v0.3.11'}
git clone --depth 1 --branch ${BLST_VERSION} https://github.com/supranational/blst
cd blst
./build.sh
cat > libblst.pc << EOF

sudo chmod u=rw,go=r /usr/local/{lib/{libblst.a,pkgconfig/libblst.pc},include/{blst.{h,hpp},blst_aux.h}}
```

## Configuring the build options

We explicitly use the `ghc` version that we installed earlier. This avoids defaulting to a system version of `ghc` that might be newer or older than the one you have installed.
