Tao He updated ARROW-11836:
---------------------------
Description:
When ``-DARROW_BUILD_STATIC=ON``, all build dependencies built as static
libraries by the Arrow build system will be merged together to create a static
library ``arrow_bundled_dependencies``.
But that is only true when there are indeed some dependencies, i.e., when
``ARROW_BUNDLED_STATIC_LIBS`` is not empty [1]. It could be empty when we just
enable some of features when building arrow (e.g., just the arrow core).
However the target is unconditionally required by the target ``arrow_static``
[2]. That makes the staticly-built arrow libs cannot be used with cmake.
