Build Configuration

Intro

Intel RealSense SDK is using CMake eco-system to offer useful customization to customers who wish to build the SDK from source.

For example, to generate makefile with BUILD_EXAMPLES flag turned-on, use the following command line: cmake .. -DBUILD_EXAMPLES=true Alternatively, use cmake-gui utility to configure and generate your build files.

Build Customization Flags

Flag	Description	Default
BUILD_EXAMPLES	Build SDK examples and tools	false
BUILD_GRAPHICAL_EXAMPLES	Controls the-subset of examples and tools dependent on OpenGL. Disabling this option will reduce the set of tools and examples to rs-save-to-file, rs-terminal, rs-enumerate-devices and rs-fw-logger. Recommended for headless systems without the graphic subsystem	true
BUILD_UNIT_TESTS	Build the full suite of unit-tests for the SDK	true
BUILD_WITH_OPENMP	When enabled, YUY to RGB conversion and Depth-Color spatial alignment will take advantage of multiple-cores using OpenMP. This can reduce latency at expense of greater CPU utilization	true
ENFORCE_METADATA	Having UVC per-frame metadata requires building with Windows SDK installed. When this flag is disabled, the resulting binary might not be capable of properly parsing UVC metadata if Windows SDK was not installed during the build. If this flag is true, not having Windows SDK install will break the build	false
BUILD_PYTHON_BINDINGS	Build Python bindings for the SDK. Requires Python to be installed. See wrapper page for more information	false
BUILD_NODEJS_BINDINGS	Build Node.js bindings for the SDK. Requires Node.js to be installed. See wrapper page for more information	false
FORCE_LIBUVC	Setting this flag to true will configure the underlying backend to use libuvc. This backend is default for Mac OS, but can be configured on other OS-s as well. libuvc can serve as a more robust alternative to the native backend, however, it has well known limitations and is not recommended to be used in end-products	false
TRACE_API	When this flag is enabled, all API-calls will be written to the log at INFO severity. This will include any errors, duration, input and output parameters as well as the return value. Entry and exit from API calls will be documented as well at DEBUG severity. Enabling this feature will result in severe performance penalty	false
HWM_OVER_XU	When this option is enabled, hardware commands will be dispatched through extension-unit (XU) transfer protocol. When disabled (and assuming the hardware supports it) the SDK will talk to the hardware directly using libusb / WinUSB	true
BUILD_SHARED_LIBS	When enabled the output of the library will be a dynamic link library (DLL) or a shared object (SO). When disabled the output will be a static library (LIB/A)	true
CMAKE_BUILD_TYPE	Desired build time. To take advantage of compiler optimizations set to "Release" or "RelWithDebInfo"	Debug
