Fail to build xgboost.federated plugin

[yan-gao-GY]

Hi, I tried to install the plugin xgboost.federated following the instruction here (https://github.com/dmlc/xgboost/tree/master/plugin/federated), but I got an error as below:

CMake Error at CMakeLists.txt:12 (xgboost_target_properties): Unknown CMake command "xgboost_target_properties".

I have updated CMake, and installed gRPC. Then I ran these commands:

mkdir build 
cd build 
cmake .. -GNinja \ 
-DPLUGIN_FEDERATED=ON \ 
-DUSE_CUDA=ON\ 
-DUSE_NCCL=ON 
ninja 
cd ../python-package 
pip install -e . 

The error appeared when running cmake. Could you please indicate me how to fix this error? What's the correct way to install this plugin? Thanks a lot!

which cmake version are you using?

[yan-gao-GY]

3.27.9

[trivialfis]

I'm using the same version from conda forge, I can't reproduce it

Oh I forgot to mention that I ran it on macbook with cmake .. -GNinja -DPLUGIN_FEDERATED=ON

[trivialfis]

I don't think macos has CUDA support, or NCCL.

I don't have a mac, have to wait for @hcho3 .

[yan-gao-GY]

Yes, I didn't pass the cuda and nccl arguments

Closing as we haven't been able to reproduce. For reference, the missing command shared in the issue is defined here: https://github.com/dmlc/xgboost/blob/033a666900a2b58f72a3050e63b02f1681e4f609/cmake/Utils.cmake#L165 .
