Subject: [PATCH] Updated build instructions (#3573)

Building on Ubuntu 18.04 no longer works as documented

```
CMake Error at lib/settings/CMakeLists.txt:132 (message):
  GCC version must be at least 8.0 if using std filesystem
```

I verified the build instructions on Ubuntu 20.04 and they work as advertised.

For Ubuntu 18.04, you'd have the option of
1) Manually installing a later version of GCC
2) Using clang
3) passing the `-DPAJLADA_SETTINGS_USE_BOOST_FILESYSTEM=1` flag to cmake
