Question about cmake settings

[boxerab]

1. I see there is standard BUILD_SHARED_LIBS option and also a onnxruntime_BUILD_SHARED_LIB option. What is the second option for?
2. When I set onnxruntime_USE_CUDA option, is it possible to read onnxruntime_CUDNN_HOME from an environment variable ? Currently I have to manually set it.

In general, are the cmake options documented anywhere ?

Thanks!

No, BUILD_SHARED_LIBS is totally different. It means replaces every "add_library(...)" to "add_library(... SHARED ..)". It won't work. I insist on one thing: you can't simply convert a static library to a shared library without impacting the library's behavior. And in many many case it will make the library unusable. So BUILD_SHARED_LIBS is just a for convenient for some simple cases.

Makes sense, thanks.
