Missing gz-cmake4 building sources with Ubuntu 24.04

[rbonghiNV]

Hi team, I'm trying to install and use this tool to convert the sdf files, but with Ubuntu 24.04 I encountered the error below:

Environment

• OS Version: Ubuntu 24.04
• main source

Steps to reproduce

Follow the main documentation in https://github.com/gazebosim/gz-usd
Error when executed: cmake .. in

git clone https://github.com/gazebosim/gz-usd
cd gz-usd
mkdir build
cd build
export GZ_VERSION=<harmonic or ionic>
cmake ..

Output

CMake Error at CMakeLists.txt:26 (find_package):
  By not providing "Findgz-cmake4.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "gz-cmake4", but CMake did not find one.

  Could not find a package configuration file provided by "gz-cmake4" with
  any of the following names:

    gz-cmake4Config.cmake
    gz-cmake4-config.cmake

  Add the installation prefix of "gz-cmake4" to CMAKE_PREFIX_PATH or set
  "gz-cmake4_DIR" to a directory containing one of the above files.  If
  "gz-cmake4" provides a separate development package or SDK, be sure it has
  been installed.

Hello @rbonghiNV ! The docs refer to the sdformat installation, but I think that only Gazebo Harmonic (sdformat14) or Gazebo Ionic are currently supported (sdformat15). Which sdformat version did you installed?

Hi @traversaro !
Thank you to let me back.
I haven't installed SDFormat yet, but I'm working on the latest Gazebo for ROS kilted, which should be Ionic.

Sorry for a double message.
I installed

sudo apt install libsdformat15

and rerun again the

cmake ..

But I encour on the same error.

Thank you in advance for any help

If you are using ROS, probably it is better to use Gazebo Vendors package (see https://gazebosim.org/docs/ionic/ros2_gz_vendor_pkgs/). So you should install sdformat with:

sudo apt install ros-kilted-sdformat-vendor

Hi @traversaro ,

I canceled my previous post. I fixed the issue.

A new error has appeared, and I'm still working on fixing it. I will inform you in the next update if I am unable to resolve it. Thank you in advance for your support.
