- Only build the specified libraries. `Asio` itself is header only so doesn’t have to be built.
- Only build static libraries (`link=static`)
- The number after `-j` depends on the number of CPU cores you have.
- If you want to build release version libraries, set `variant=release`. The `debug` and `release` libraries have exactly the same name, so you cannot build them both at the same time.
- Don’t forget the `sudo` since the install prefix is `/usr/local`.
To clean the build, run `b2` with target "clean":
```
./b2 clean
```
The libraries are installed to `/usr/local/lib`. E.g.,
## Install Zlib & OpenSSL
```
$ ls -l /usr/local/lib/libboost*
