Requirements:

1. Running requires

   • Ultraleap Tracking Software https://developer.leapmotion.com/get-started/

2. Building Samples requires

   • CMake 3.16.3+ (https://cmake.org/)
   • Microsoft Visual Studio 15+ (Windows)
   • GCC (Linux - tested on v9.4.0)

Installation:

The LeapSDK is installed with Ultraleap Tracking.

Usage:

1. For CMake projects

   • Ensure LeapSDK is in a directory considered as a prefix by find_package. (https://cmake.org/cmake/help/v3.16/command/find_package.html)
     • Or : directly set LeapSDK_DIR to <install_dir>/LeapSDK/lib/cmake/LeapSDK
     • Or : Pass the LeapSDK's path to find_package with the PATHS option.
   • call find_package(LeapSDK 5 [PATHS ...]).
   • call target_link_libraries( PUBLIC|PRIVATE LeapSDK::LeapC).
   • Ensure LeapC.dll/LeapC.so is in your dynamic library search path.
     • A popular option is to add a post-build step that copies it to your project's output directory.

2. For non-CMake projects

   • Use a C/C++ compiler such as MSVC, Clang or GCC.
   • Add LeapSDK/include to the compiler include search paths.
   • Either add a linker reference to LeapC.lib or dynamically load LeapC.dll/LeapC.so.

Building Samples:

Windows

1. Open CMake using LeapSDK/samples as the source directory

2. Select a build directory (often LeapSDK/samples/build) to use

3. Configure & Generate CMake with the generator of your choice

4. Open and build the CMake generated project files. For more help, see the CMake documentation.

   • An example script would be :

$env:BUILD_TYPE = 'Release'
$env:REPOS_BUILD_ROOT = 'C:/build'
$env:REPOS_INSTALL_ROOT = 'C:/Program Files'

cmake -S "C:/Program Files/Ultraleap/LeapSDK/samples" -B $env:REPOS_BUILD_ROOT/$env:BUILD_TYPE/LeapSDK/leapc_example `
		-DCMAKE_INSTALL_PREFIX="$env:REPOS_INSTALL_ROOT/leapc_example" `
		-DCMAKE_BUILD_TYPE="$env:BUILD_TYPE"

cmake --build $env:REPOS_BUILD_ROOT/$env:BUILD_TYPE/LeapSDK/leapc_example -j --config $env:BUILD_TYPE

x64 Linux

1. Open CMake using /usr/share/doc/ultraleap-hand-tracking-service/samples as the source directory

2. Select a build directory (eg. ~/ultraleap-tracking-samples/build) to use

3. Configure & Generate CMake with the generator of your choice

4. Open and build the CMake generated project files. For more help, see the CMake documentation.

   • An example script would be :

SRC_DIR=/usr/share/doc/ultraleap-hand-tracking-service/samples    
BUILD_TYPE='Release'    
REPOS_BUILD_ROOT=~/ultraleap-tracking-samples/build     
REPOS_INSTALL_ROOT=/usr/bin/ultraleap-tracking-samples    
    
cmake -S ${SRC_DIR} -B ${REPOS_BUILD_ROOT}/${BUILD_TYPE}/LeapSDK/leapc_example `       
        -DCMAKE_INSTALL_PREFIX="${REPOS_INSTALL_ROOT}/leapc_example" `    
        -DCMAKE_BUILD_TYPE="${BUILD_TYPE}"    
    
cmake --build ${REPOS_BUILD_ROOT}/${BUILD_TYPE}/LeapSDK/leapc_example -j --config ${BUILD_TYPE}    

MacOS

1. Open CMake using /Library/Application Support/Ultraleap/LeapSDK/samples as the source directory

2. Select a build directory (eg. ~/ultraleap-tracking-samples/build) to use

3. Configure & Generate CMake with the generator of your choice

4. Open and build the CMake generated project files. For more help, see the CMake documentation.

   • An example script would be :

SRC_DIR='/Library/Application Support/Ultraleap/LeapSDK/samples'
BUILD_TYPE='Release'
REPOS_BUILD_ROOT=~/ultraleap-tracking-samples/build
REPOS_INSTALL_ROOT=~/ultraleap-tracking-samples/bin

cmake -S ${SRC_DIR} -B ${REPOS_BUILD_ROOT}/${BUILD_TYPE}/LeapSDK/leapc_example `
-DCMAKE_INSTALL_PREFIX="${REPOS_INSTALL_ROOT}/leapc_example" `
-DCMAKE_BUILD_TYPE="${BUILD_TYPE}"

cmake --build ${REPOS_BUILD_ROOT}/${BUILD_TYPE}/LeapSDK/leapc_example -j --config ${BUILD_TYPE}
