Once you have installed the Vulkan SDK and compiled vkav, run the command
$ ./build.sh VULKAN_SDK_PATH
where VULKAN_SDK_PATH is the absolute path to the vulkan sdk. The script will build a .app bundle which can
then be installed to the applications directory.
Note: the script does not package application dependencies
You may want to create a symlink from /usr/local/bin to Vkav.app/Contents/Macos/start.sh to allow vkav to be run from the command line.
