A condensed vulkan triangle example

I recommend installing the vulkan lunarG sdk which sets all of the environment variables for you and includes the necessary shaderc library prebuilt for you.

then you can install the dependecies with vcpkg

vcpgk install glfw3

then you can invoke cmake with

cmake -DCMAKE_TOOLCHAIN_FILE=C:\pathtoyourtoolchainfile\vcpkg.cmake ..

if you've forgotten where your toolchain file is you can invoke vcpkg integrate install and it will print it for you in the terminal.

then to build on windows invoke cmake --build . --config Release (other platforms you can just invoke cmake --build)

vulkanhppminimalexample's Issues

physicalDevice selection issue

Was compiling a few vulkan tutorials I found on the web and came across yours. Line 73-76 in main.cpp:

    auto physicalDevice = physicalDevices[std::distance(physicalDevices.begin(),
        std::find_if(physicalDevices.begin(), physicalDevices.end(), [](const vk::PhysicalDevice& physicalDevice) {
            return strstr(physicalDevice.getProperties().deviceName, "Intel");
        }))];

This crashes the program with a 'vector subscript out of range' when there's only one device in the enumeration and it doesn't matchs the substring you've defined ("Intel").

Built with cmake + ninja in VS2022 on Windows 10v19044.2846, with an nVidia 1070 using driver version 528.33. Just selecting the first physical device using auto physicalDevice = physicalDevices[0] was a workaround for this system, which only enumerates a single physical device (the 1070).
