# Instructions for the user:
# 1. Install CMake (https://cmake.org/download/)
# 2. Set the three paths at the top of this file (MAYA_LOCATION, OpenCV_DIR, MEDIAPIPE paths).
# 3. Create a 'build' directory inside this project folder.
# 4. Open a command prompt or terminal in the 'build' directory.
# 5. Run CMake to generate the project files for your compiler:
#    For Visual Studio: cmake -G "Visual Studio 16 2019" ..
#    For Makefiles:    cmake ..
# 6. Compile the project:
#    For Visual Studio: cmake --build . --config Release
#    For Makefiles:    make
# 7. The compiled facialPerformanceNode.mll will be in the 'build/Release' directory.
# 8. Copy the .mll file to your Maya plug-ins directory (e.g., C:/Users/YourUser/Documents/maya/2023/plug-ins).
