macOS build steps

The build steps for macOS align closely with those for CentOS 7, documented by Dreamworks here

But of course, with a few tweaks.

Base requirements:

• macOS Sonoma (macOS 14)
• Install Xcode
• Download and install CMake 3.26.5 https://github.com/Kitware/CMake/releases/download/v3.26.5/cmake-3.26.5-macos-universal.dmg sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install

Create a clean root folder for moonray, and follow the next three steps:

1. Create the folders mkdir -p /Applications/MoonRay/{installs,build,build-deps,source} mkdir -p /Applications/MoonRay/installs/{bin,lib,include}

2. Check out the OpenMoonRay source - alongside installs/ cd /Applications/MoonRay/source git clone --recurse-submodules cd .. ln -s source/openmoonray/building . ln -s source/openmoonray .

3. Build the dependencies - alongside source/ and installs/ cd /Applications/MoonRay/build-deps cmake ../building/macOS Only if building for Houdini, replace above with: cmake -DNO_USD=1 ../building/macOS cmake --build .

4. Build MoonRay cd /Applications/MoonRay/openmoonray cmake --preset container-macOS Only if building for Houdini, replace above with: cmake --preset container-macOS-houdini cmake --build --preset container-macOS

5. Run / test source /Applications/MoonRay/installs/openmoonray/scripts/setup.sh cd /Applications/MoonRay/openmoonray/testdata moonray_gui -exec_mode xpu -info -in curves.rdla

6. Cleanup rm -rf /Applications/MoonRay/{build,build-deps,openmoonray/release}

HOUDINI:

open Houdini Terminal in Applications source /Applications/MoonRay/openmoonray/scripts/macOS/setupHoudini.sh houdini

in the Scene View tab on the main window, change from "obj" to "stage" click on Sphere and click on the viewport to place in on the "stage" on the viewport, click on "Persp" and select "Moonray", this should trigger the rendering, etc...
