CMake build broken with rootproject/root:latest image

[jdfrankland]

Dear root-project,

After updating to the latest image I can no longer use ROOT in a CMake project.

The following minimal CMakeLists.txt:

cmake_minimum_required(VERSION 3.16)
project(myProject)
find_package(ROOT REQUIRED)

gives the following output:

$ cmake -B build

  (requested version 3.10.5) with any of the following names:

    nlohmann_json-config.cmake

  Add the installation prefix of "nlohmann_json" to CMAKE_PREFIX_PATH or set
  "nlohmann_json_DIR" to a directory containing one of the above files.  If
  "nlohmann_json" provides a separate development package or SDK, be sure it
  has been installed.

If I install the nlohmann-json3-dev package with apt and try again, I get further errors:

$ rm -rf build

Any help woud be greatly appreciated (please note that I have been using previous versions of this image in my CI for a long time, there was never a problem before)

I just ran into the same issue with the rootproject/root:6.30.02-ubuntu22.04 image as described above, I also want to use the image in a CI. I see that the issue is closed, but the container was not updated?

[ferdymercury]

@linev fixed it for the future 6.30.04 release I guess

[linev]

No, I only change it in master - one need to backport it.

[harrypuuter]

Thanks for the quick replies, I will wait for a new release then!

This is backport to 6.30 branch. Will be released soon with 6.30.04 version

[martamaja10]

the 6.30.04 version (ubuntu22.04) is now available as the latest image
