Cmake FindArrow variables not set properly

Hi all,

I am trying to use cmake find_package in my project (inside a conda env). I
have the following in the cmake file.

    message("Finding Arrow from SYSTEM")
    find_package(Arrow ${CYLON_ARROW_VERSION} CONFIG REQUIRED)
    message(STATUS "Arrow found: ${ARROW_FOUND}")
    message(STATUS "Arrow ver: ${ARROW_FULL_SO_VERSION}")
    message(STATUS "Arrow include dir: ${ARROW_INCLUDE_DIR}")
    message(STATUS "Arrow lib dir: ${ARROW_LIB_DIR}")

    find_library(ARROW_SO arrow ${CYLON_ARROW_VERSION})
    message(STATUS "Arrow lib: ${ARROW_SO}")

    find_library(ARROW_PY_SO arrow_python ${CYLON_ARROW_VERSION})
    message(STATUS "Arrow py lib: ${ARROW_PY_SO}")

Following is my output.

Finding Arrow from SYSTEM
-- Arrow found:
-- Arrow ver: 400.1.0
-- Arrow include dir:
-- Arrow lib dir:
-- Arrow lib: /aux/miniconda/envs/cylon_dev/lib/libarrow.so
-- Arrow py lib: /aux/miniconda/envs/cylon_dev/lib/libarrow_python.so

It seems to be that the CMake variables like, ARROW_FOUND,
ARROW_INCLUDE_DIR, etc are not set properly. But cmake can still locate the
.so files without a problem.

When I explicitly call the FindArrow.cmake file in the
${CONDA_PREFIX}/lib/cmake/arrow dir,
find_package(Arrow CONFIG REQUIRED CONFIGS FindArrow.cmake HINTS
${CONDA_PREFIX}/lib/cmake/arrow)

I get the following cmake warning, but then all variables are set properly.
Finding Arrow from SYSTEM

(message):
  The package name passed to `find_package_handle_standard_args` (PkgConfig)
  does not match the name of the calling package (Arrow).  This can lead to
  problems in calling code that expects `find_package` result variables

This warning is for project developers.  Use -Wno-dev to suppress it.

-- Arrow py lib: /aux/miniconda/envs/cylon_dev/lib/libarrow_python.so

When we are using Arrow in an external project, should I copy the
FindArrow.cmake file to that project explicitly, and then use it?

Hi Sutou,
I think this is a problem with my IDE. When I am running inside a terminal,
it seems to be working fine. :-/

Hi,

Could you remove CONFIG from find_package(Arrow)?

Thanks,
