Question: Run `compile_example` in call to `install_cmdstan` even if already installed?

The install_cmdstan script verifies the installation by calling compile_example after (re)-building cmdstan. Should we also call it after identifying that cmdstan is already installed to check the installation is functional (or add a flag to compile the example if cmdstan is already installed)? The main motivation is that sometimes the existing installation breaks, e.g., due to precompiled header changes.

I think this is a good idea

Alright, will put together a PR. Preference for

  • always run compile_example
  • don't run compile_example by default but add a flag to run it
  • run compile_example by default but add a flag to not run it?

I think it is fine to always do it. We may want to check if the executable exists and delete it first
