Development tools:

• cmake (3.13+)
• a build tool (GNU make, ninja, IDE-provided, etc.)
• C++17 compatible compiler (e.g. GCC (8+) or clang (5+))

Preinstalled libraries:

• SDL2¹
• SDL2_ttf (2.20.1+)²

$ cmake -S . -B build # -G Ninja, etc.
$ cd build
$ make                # ninja, etc.

If your distribution provides the latest release version of SDL2_ttf library, you may use the system package manager to install it. Otherwise, get the source disribution from the distribution page², build and install the library manually. When installing to non-standard location <sdl2ttf-dir>, provide the path to the cmake configuration step:

$ cmake -S . -B build -DCMAKE_PREFIX_PATH=<sdl2ttf-dir>

Get the appropirate development releases from the distribution page³, unpack and copy contents of the archived directories to the same location <install-prefix>. Then provide the path to the cmake configuration step:

$ cmake -S . -B build -DCMAKE_PREFIX_PATH=<install-prefix>

If an IDE is in use, find the IDE cmake configuration options and provide the -DCMAKE_PREFIX_PATH=<install-prefix> option accordingly.

Homebrew package manager provides the latest library versions:

$ brew install sdl2 sdl2_ttf
