cmake . && make

You could add dependencies manually but it is easier to use Conan.

First, set up your Conan profile to match your compiler or let conan autodetect your settings (conan profile new vs --detect and use --profile=vs when running conan install). Visual Studio 2019 profile should look like this:

[settings]
os=Windows
os_build=Windows
arch=x86_64
arch_build=x86_64
compiler=Visual Studio
compiler.version=16
build_type=Debug

Then open 'Developer PowerShell for Visual Studio' and execute the following commands:

conan install . --build missing
cmake .
devenv /build Debug falltergeist.sln

(or open and build the solution in Visual Studio instead of running the devenv command)

Put master.dat and critter.dat files into the falltergeist data directory, that is

• ~/.local/share/falltergeist/ or /usr/local/share/falltergeist (for global installs) on Linux,
• ~/Library/Application Support/falltergeist on OS X,
• %APPDATA%/falltergeist on Windows,

or mount CD-ROM with original game, then run ./falltergeist on *nix or .\bin\falltergeist.exe on Windows.

This is a pretty highlevel roadmap to get to a playable game. The idea behind it is to step by step get closer to the full game.
