[C++] Dependency issue for cmake

[jtristano]

Describe the usage question you have. Please include as many useful details as possible.

Hi,
I'm trying to build arrow into my cmake c++ project.

I installed all of the packages here --- https://arrow.apache.org/install/

I followed the instructions on the build page for cmake but that wasnt enough....

I had to do this

# Add re2 package
FetchContent_Declare(
  re2
  GIT_REPOSITORY https://github.com/google/re2.git
  GIT_TAG 2024-07-02
)
FetchContent_MakeAvailable(re2)

Then cmake complained some more about abseil.. added this

# Add Abseil
FetchContent_Declare(
  abseil
  GIT_REPOSITORY https://github.com/abseil/abseil-cpp.git
  GIT_TAG        20230125.1
)
FetchContent_MakeAvailable(abseil)

I also use nlohmann so I had to do this

if(NOT TARGET nlohmann_json)
  FetchContent_Declare(
    json
    URL https://github.com/nlohmann/json/releases/download/v3.11.2/json.tar.xz
  )
  FetchContent_MakeAvailable(json)
endif()

Then I had to ask copilot for help in resolving all of this....

-- Configuring done (12.8s)
CMake Error: install(EXPORT "re2Targets" ...) includes target "re2" which requires target "absl_absl_check" that is not in any export set.
CMake Error: install(EXPORT "re2Targets" ...) includes target "re2" which requires target "absl_absl_log" that is not in any export set.
-- Generating done **(0.3s)**

Not being a cmake expert, I'm stuck between removing this and getting re2 included twice. Copilot is stuck here and so am I.

Any help in being able to successfully link against developer packages. I dont want to build from source if I dont have to.

Some cmake info if it helps

I installed all of the packages here --- https://arrow.apache.org/install/

What is your environment? What packages were you installed?

I followed the instructions on the build page for cmake but that wasnt enough....

Could you show the URL of "the build page for cmake"?

Could you show what you did in your CMake configuration?
It seems that you didn't use find_package(Arrow REQUIRED) or something.

[jtristano]

I have

find_package(Arrow REQUIRED)

in my cmake as well as all of the instructions found here:
https://arrow.apache.org/docs/cpp/build_system.html

Could you answer all of my questions?
I can't help you without them.

It seems that a combination of the minimal docker compose and the instructions on the build
Page are getting me there. I need to update my docker file from all of the manual edits that I made and will update this thread with the results. The documentation may just need some updating.
