I've built ONNX Runtime for Windows from scratch by cloning https://github.com/microsoft/onnxruntime and running the build.bat script. It successfully called down to CMake and compiled and generated a bunch of files into the build/Windows/RelWithDebInfo directory.
Now I want to install the library to my system.
I'm used to the Linux world where there is usually a Makefile and then I can run sudo make install.
I've ran cmake --install . from the RelWithDebInfo directory, but this produced
cmake --install .
-- Install configuration: "Release"
CMake Error at cmake_install.cmake:36 (file):
file cannot create directory: C:/Program
Files/onnxruntime/include/onnxruntime. Maybe need administrative
privileges.
This is strange because the configuration is wrong. It's not supposed to be "Release" it's supposed to be "RelWithDebInfo."
How to install proper configuration?
You configure the project for Visual Studio generator, which is multi-configuration one. Because of that, it is pretty irrelevant what name has the directory with your build files (build/Windows/RelWithDebInfo): this directory contains build files sufficient for build the project in any configuration (supported by the project).
For install a specific configuration of the project with cmake --install just pass appropriate --config parameter:
cmake --install . --config RelWithDebInfo
