Just faced/resolved this issue myself. CMake will autogenerate .cxx files which contain your local user paths to NDK related files. Thus, as one of the above comments mentioned, a remote platform like Azure obviously wont find such path.

You should also be able to reproduce this error locally on a different machine with a different User.

To resolve, I deleted the .cxx folder from my local and added ".cxx" to the gitignore. Push these changes to remote and it should resolve the error.
