a43b8e955558483d8893996cc3a67bc74cbaf358 build: set OSX_MIN_VERSION to 10.15 (fanquake) Pull request description: Taken out of #20744, as splitting up some of the build changes was mentioned [here](https://github.com/bitcoin/bitcoin/pull/22937#discussion_r707303172). This is required to use `std::filesystem` on macOS, as support for it only landed in the libc++.dylib shipped with 10.15. So if we want to move to using `std::filesystem` for `23.0`, this bump is required. See also: https://developer.apple.com/documentation/xcode-release-notes/xcode-11-release-notes > Clang now supports the C++17 \<filesystem\> library for iOS 13, macOS 10.15, watchOS 6, and tvOS 13. macOS 10.15 was released in October 2019. macOS OS's seem to have a life of about 3 years, so it's possible that 10.14 will become officially unsupported by the end of 2021 and prior to the release of 23.0.

CI Scripts
This directory contains scripts for each build step in each build stage.
Running a Stage Locally
Be aware that the tests will be built and run in-place, so please run at your own risk. If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory. While most of the actions are done inside a docker container, this is not possible for all. Thus, cache directories, such as the depends cache, previous release binaries, or ccache, are mounted as read-write into the docker container. While it should be fine to run the ci system locally on you development box, the ci scripts can generally be assumed to have received less review and testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci system in a virtual machine with a Linux operating system of your choice.
To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage
requires docker to be installed. To install all requirements on Ubuntu, run
sudo apt install docker.io bash
To run the default test stage,
./ci/test_run_all.sh
To run the test stage with a specific configuration,
FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
Configurations
The test files (FILE_ENV) are constructed to test a wide range of
configurations, rather than a single pass/fail. This helps to catch build
failures and logic errors that present on platforms other than the ones the
author has tested.
Some builders use the dependency-generator in ./depends, rather than using
the system package manager to install build dependencies. This guarantees that
the tester is using the same versions as the release builds, which also use
./depends.
If no FILE_ENV has been specified or values are left out, 00_setup_env.sh
is used as the default configuration with fallback values.
It is also possible to force a specific configuration without modifying the file. For example,
MAKEJOBS="-j1" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
The files starting with 0n (n greater than 0) are the scripts that are run
in order.
Cache
In order to avoid rebuilding all dependencies for each build, the binaries are cached and re-used when possible. Changes in the dependency-generator will trigger cache-invalidation and rebuilds as necessary.
