Super Mario 64 on DragonflyBSD 5.9-DEVELOPMENT
1. The build environment
You'll need a few things in place. DragonflyBSD isn't Linux, and it isn't OSX, and the project doesn't actually consider building on *BSD. So we need to do a few things before we can build it. The commands below will install the dependencies we'll be compiling-with/linking-against, clone the repository, and create the appropriate symlinks the Makefile currently expects.
doas pkg install gcc9 sdl2 python3 libGLU glew
git clone https://github.com/sm64pc/sm64ex.git
cd sm64ex/
ln -s /usr/include/sys/malloc.h $(pwd)/include/
ln -s /usr/local/bin/cpp9 $(pwd)/bin/cpp-9
ln -s /usr/local/bin/gmake $(pwd)/bin/make
export PATH=$(pwd)/bin:$PATH
2. Source material
The decompilation of Mario 64 is seriously cool. But unlike code which you can maybe get away with - you really can't get away with redistributing the sound effects, music, and artwork. So you'll need a copy of the game on hand, placed in the project root. I've provided the sha256 sum of the file I used, as a reference. Yours may differ.
sha256 baserom.us.z64
SHA256 (baserom.us.z64) = 17ce077343c6133f8c9f2d6d6d9a4ab62c8cd2aa57c40aea1f490b4c8bb21d91
3. File changes
Before building, we want to make a few small changes. In the main Makefile , we want to remove its attempt at OS detection. Currently this will cause the build to assume we're running some form of Windows, causing it to go looking for mingw:
diff --git a/Makefile b/Makefile
index 8360415..b501b25 100644

We also need to make a small change to src/pc/gfx/gfx_opengl.c to properly pull in GLEW. This codeblock was originally intended for MacOS - but we can make use of it:

4. Building and Running
With everything ready, we can now build. The end result should be a directory in build/ for your region. In my case this was build/us_pc/sm64.us.f3dex2e.
Performance will vary based on your machine, but you do have the option of setting the GL/LEGACY render API, or setting GRUCODE to f3d/new. See the Makefile for all your options!
$ make BETTERCAMERA=1 EXTERNAL_DATA=1 DEBUG=0 -j4
$ ./build/us_pc/sm64.us.f3dex2e
