Merge bitcoin/bitcoin#31161: cmake: Set top-level target output locations
568fcdddaec2cc8decba5a098257f31729cc1caa scripted-diff: Adjust documentation per top-level target output location (Hennadii Stepanov)
026bb226e96919603af829d0b677779a234a0f6e cmake: Set top-level target output locations (Hennadii Stepanov)

Pull request description:

  This PR sets the target output locations to the `bin` and `lib` subdirectories within the build tree, creating a directory structure that mirrors that of the installed targets.

  This approach is widely adopted by the large projects, such as [LLVM](e146c1867e/lldb/cmake/modules/LLDBStandalone.cmake (L128-L130)):
  ```cmake
  set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
  set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
  set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
  ```

  The `libsecp256k1` project has also recently [adopted](https://github.com/bitcoin-core/secp256k1/pull/1553) this approach.

  With this PR, all binaries are conveniently located. For example, run:
  ```
  $ ./build/bin/fuzz
  ```
  instead of:
  ```
  $ ./build/src/test/fuzz/fuzz
  ```

  On Windows, all required DLLs are now located in the same directory as the executables, allowing to run `bitcoin-chainstate.exe` (which loads `bitcoinkernel.dll`) without the need to copy DLLs or modify the `PATH` variable.

  The idea was briefly discussed among the build team during the recent CoreDev meeting.

  ---

  **Warning**: This PR changes build locations of newly built executables like `bitcoind` and `test_bitcoin` from `src/` to `bin/` without deleting previously built executables. A clean build is recommended to avoid accidentally running old binaries.

    Code review ACK 568fcdddaec2cc8decba5a098257f31729cc1caa. Only change since last review was rebasing. I'm ok with this PR in its current form if other developers are happy with it. I just personally think it is inappropriate to \*silently\* break an everyday developer workflow like `git pull; make bitcoind`. I wouldn't have a problem with this PR if it triggered an explicit error, or if the problem was limited to less common workflows like changing cmake options in an existing build.

Bitcoin Core

Setup

Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.

To download Bitcoin Core, visit bitcoincore.org.

Running

The following are some helpful notes on how to run Bitcoin Core on your native platform.

Unix

Unpack the files into a directory and run:

  • bin/bitcoin-qt (GUI) or
  • bin/bitcoind (headless)

Windows

Unpack the files into a directory, and then run bitcoin-qt.exe.

macOS

Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
