namely [cpp-httplib](https://github.com/yhirose/cpp-httplib). First off,
set a directory where the cpp-httplib install will go:

```shell
export CPPHTTPLIB_SRC_DIR=~/cpphttplib
export CPPHTTPLIB_INSTALL_DIR=~/cpp-httplib-install
```

Then clone the repository and build:

```shell
git clone https://github.com/yhirose/cpp-httplib $CPPHTTPLIB_SRC_DIR
mkdir $CPPHTTPLIB_SRC_DIR/build
cd $CPPHTTPLIB_SRC_DIR/build
cmake -GNinja \
-DHTTPLIB_NO_EXCEPTIONS=ON \
-DCMAKE_INSTALL_PREFIX=$CPPHTTPLIB_INSTALL_DIR \
../
ninja install
```
