Change #272956

Comments

cmake: flatten build tree, tidy up base dir variables
- drop `generated` subdir, move these files to build root.
  To move them next to CPack and other config files, and to avoid
  a subdirectory for only 2 files.

- add 'Consumed variables' comment for `CMake/cmake_uninstall.in.cmake`.

- move generated `cmake_uninstall.cmake` to the build root directory
  (from `CMake/`). To:
  - avoid creating a `CMake` subdirectory within the build directory
    with this single file in it.
  - move it next to its `cmake_install.cmake` counterpart.
  - move it next to `install_manifest.txt` which it relies on.

- Use `PROJECT_SOURCE_DIR` for these files, replacing
  `CMAKE_CURRENT_SOURCE_DIR`, to make it consistent with rest of CMake
  sources, and to reduce ambiguity in `CMake/cmake_uninstall.in.cmake`
  template.
