-------------------------------------

             Summary: arrowTargets.cmake is broken
                 Key: ARROW-4065
                 URL: https://issues.apache.org/jira/browse/ARROW-4065
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
    Affects Versions: 0.12.0
            Reporter: Kousuke Saruta
            Assignee: Kousuke Saruta


When we build Arrow's cpp library using CMake, arrowTargets.cmake will be generated and installed but it's broken.

The following is a part of arrowTargets.cmake generated.

{code}
# Create imported target arrow_shared
add_library(arrow_shared SHARED IMPORTED)

set_target_properties(arrow_shared PROPERTIES
  INTERFACE_LINK_LIBRARIES "dl;pthreadshared"
)

# Create imported target arrow_static
add_library(arrow_static STATIC IMPORTED)

set_target_properties(arrow_static PROPERTIES
  INTERFACE_LINK_LIBRARIES "glog_static;zstd_static;zlib_shared;snappy_static;lz4_static;brotli_dec_static;brotli_enc_static;brotli_common_static;double-conversion_static;boost_system_shared;boost_filesystem_shared;boost_regex_shared;jemalloc_static;rt;pthreadshared"
)
{code}

There are no INTERFACE_INCLUDE_DIRECTORIES and linker doesn't recognize pthreadshared because the true name of pthread lib should be libpthread.so or libpthread.a.
*_static and *_shared are also wrong name.

Because of this, apps which links arrow can't be built using CMake.
