Missing pthread.h and Vulcan when running cmake on Windows #47

Closed Puneet-G closed 5 years ago

Puneet-G commented 5 years ago

When I run cmake, the follow two error lines come up:

Looking for pthread.h - not found Could NOT find Vulkan (missing: VULKAN_LIBRARY VULKAN_INCLUDE_DIR)

Everything else seems to be fine. Is there something I'm missing and should install?

Here is the full output when running cmake ..

It's not an issue. GLFW tries to use Vulkan if it can find it, but if not, it falls back on OpenGL.

Cool, thanks!

So the pthread.h missing is a non-issue as well?

Yes it's not an issue. You'll see that directly below that line that it found the Threads library instead, which fulfills the same purpose. In general, if cmake runs into an issue it can't recover from, it will tell you that it finished with errors. When it says stuff like "configuring done, generating done", it means that it finished successfully.

Thanks Abhi! Appreciate it :)
