Note: You may try using windows, but last time I checked there was a problem with the completion engine (nvim-cmp) that makes it impossible to traverse the drop-down list.

Optional

The following are optional but provides additional features:

make
gcc and g++
npm
python3 with venv
java runtime
shellcheck

The sections below describes this in more detail.

Treesitter

Some parsers require tools for compilation, like gcc and/or g++. There are far too many parsers for me to list (and keep track of) all their dependencies here, but gcc and g++ should cover a lot of them. You will generally encounter an error that describes if something is missing upon opening specific filetypes, because treesitter is configured to automatically install parsers when needed.

LuaSnip

jsregexp is required in order to perform some transformations. See here for more information. You don't need to install this yourself, because it will attempt to compile it automatically using make and gcc. If either make or gcc is not available you might see an error in the lazy installation of LuaSnip.

Language servers

Language servers are installed automatically to the nvim data directory (:echo stdpath('data') .. '/mason'). The following are some noted requirements for the installations themselves:

diagnostic-languageserver: npm
bash-language-server: npm
cmake-language-server: python3 with venv
jedi-language-server: python3 with venv
groovy-language-server: java

Some servers have additional runtime dependencies:

bash-language-server: shellcheck (optional, used for linting)

If you don't need some specific language server, and want to get rid of any warning messages, you may either remove them from lua/lsp/servers/init.lua or disable them in lua/lsp/servers/<server>.lua.
