SteamworksSDK

CMake integration for Valve's Steamworks SDK.

Usage

FetchContent

Integrate the SDK directly into your CMake project using FetchContent:

include(FetchContent)

FetchContent_Declare(
    SteamworksSDK
    GIT_REPOSITORY https://github.com/Waffle0823/SteamworksSDK.git
    GIT_TAG        main
)
FetchContent_MakeAvailable(SteamworksSDK)

add_executable(my_game main.cpp)
target_link_libraries(my_game PRIVATE Steamworks::API)
# Optional: encrypted app ticket library
# target_link_libraries(my_game PRIVATE Steamworks::EncryptedAppTicket)

By default the SDK is fetched from a public mirror, so no authentication is required:

cmake -B build
cmake --build build

If you disable the mirror (-DSTEAMWORKS_USE_SDK_MIRROR=OFF) the SDK is downloaded directly from Steamworks, which requires a valid steamLoginSecure cookie from a Steamworks partner account. Export it before configuring CMake:

export STEAM_LOGIN_SECURE="<your steamLoginSecure cookie>"
cmake -B build -DSTEAMWORKS_USE_SDK_MIRROR=OFF
cmake --build build

Using a pre-downloaded SDK

If you already have the SDK extracted locally, disable the download step and point CMake at its root:

cmake -B build \
    -DSTEAMWORKS_DOWNLOAD_SDK=OFF \
    -DSTEAMWORKS_SDK_ROOT=/path/to/steamworks_sdk/sdk

Options

• STEAMWORKS_DOWNLOAD_SDK (default ON): download the SDK automatically.
• STEAMWORKS_USE_SDK_MIRROR (default ON): download from the public mirror instead of Steamworks. When OFF, STEAM_LOGIN_SECURE must be set.
• STEAMWORKS_SDK_ROOT: path to an existing SDK (required when STEAMWORKS_DOWNLOAD_SDK=OFF).
• SWSDK_VERSION (default 1.64): Steamworks SDK version to download.

Exported targets

• Steamworks::API: the main steam_api shared library and headers.
• Steamworks::EncryptedAppTicket: the sdkencryptedappticket shared library and headers.

Supported platforms

• Windows: x86 (32-bit) and x64 (64-bit)
• Linux: x86 (32-bit), x64 (64-bit), and ARM64
• macOS: Universal binary
• Android: ARM64 (arm64-v8a ABI)
