Python 3 modules for LeapMotion

CMake project for building LeapMotion Python 3 modules.

Getting started

The instructions below assumes you have a Slicer build tree compiled using Visual Studio 17 2022.

Set variables

set CMAKE_EXECUTABLE=C:/cmake-3.22.1/bin/cmake.exe
set Slicer_BUILD_DIR=D:/D/S4R
set WORK_DIR=D:/T/

set LEAPMOTION_PYTHON_DISTRIBUTIONS_SOURCE_DIR=%WORK_DIR%/leapmotion-python-distributions
set LEAPMOTION_PYTHON_DISTRIBUTIONS_BUILD_DIR=%WORK_DIR%/leapmotion-python-distributions-Release
set LEAPMOTION_PYTHON_DISTRIBUTIONS_INSTALL_DIR=%WORK_DIR%/leapmotion-python-distributions-install

Download source

cd D:\T
git clone git@github.com:Slicer/leapmotion-python-distributions.git %LEAPMOTION_PYTHON_DISTRIBUTIONS_SOURCE_DIR%

Configure project

%CMAKE_EXECUTABLE% ^
  -G "Visual Studio 17 2022" ^
  -A x64 ^
  -T v143 ^
  -DCMAKE_INSTALL_PREFIX:PATH=%LEAPMOTION_PYTHON_DISTRIBUTIONS_INSTALL_DIR% ^
  -DSWIG_DIR:PATH=%Slicer_BUILD_DIR%/swigwin-4.0.2/Lib  ^
  -DSWIG_EXECUTABLE:PATH=%Slicer_BUILD_DIR%/swigwin-4.0.2/swig.exe ^
  -DPYTHON_EXECUTABLE:FILEPATH=%Slicer_BUILD_DIR%/python-install/bin/PythonSlicer.exe ^
  -DPYTHON_INCLUDE_DIR:PATH=%Slicer_BUILD_DIR%/python-install/include ^
  -DPYTHON_LIBRARY:FILEPATH=%Slicer_BUILD_DIR%/python-install/libs/python39.lib ^
  -S %LEAPMOTION_PYTHON_DISTRIBUTIONS_SOURCE_DIR% ^
  -B %LEAPMOTION_PYTHON_DISTRIBUTIONS_BUILD_DIR%

Build

%CMAKE_EXECUTABLE% ^
  --build %LEAPMOTION_PYTHON_DISTRIBUTIONS_BUILD_DIR% ^
  --config Release ^
  -- /maxcpucount:4

Install

%CMAKE_EXECUTABLE% ^
  --build %LEAPMOTION_PYTHON_DISTRIBUTIONS_BUILD_DIR%/LeapMotionPythonDistributions-build ^
  --config Release ^
  --target INSTALL ^
  -- /maxcpucount:4

Example of output:

  -- Install configuration: "Release"
  -- Installing: D:/T/leapmotion-python-distributions-install/lib/LeapC.dll
  -- Install component: "RuntimeLibraries"
  -- Installing: D:/T/leapmotion-python-distributions-install/lib/Leap.py
  -- Installing: D:/T/leapmotion-python-distributions-install/lib/_LeapPython.pyd

Verify

%Slicer_BUILD_DIR%/\python-install\bin\PythonSlicer.exe ^
  -c "import sys; sys.path.insert(0, 'D:/T/leapmotion-python-distributions-install/lib/'); import Leap; from pprint import pprint as pp; pp(dir(Leap))"
