Place the TrackpadHook.dylib binary in ~/Library/Preferences/houdini/[version]/dso in order to install.

Build from source

# Set your Houdini version (change this to your version of Houdini installation)
export VERSION=21.0.512

# Source Houdini environment
source /Applications/Houdini/Houdini$VERSION/Frameworks/Houdini.framework/Versions/Current/Resources/houdini_setup

# If you haven't cloned the repo yet:
# git clone https://github.com/mate-h/houdini-trackpad
# cd houdini-trackpad

# Create build directory and build
mkdir -p build
cd build
cmake ../src
make

The make command will automatically build and install the TrackpadHook.dylib library directly to your Houdini DSO directory (e.g., ~/Library/Preferences/houdini/21.0/dso/TrackpadHook.dylib). No separate installation step is needed - the library is ready to use after building!
