Can't build agent because of fmt

还没有人认领这个 Issue。

- Hardware description: Personnal computer running Ubuntu 24.04
- Installation type: Micro-ros-setup, colcon-build, snap
- Version or commit hash: jazzy
- Current spdlog version: 1.15.0

**Context:**
I'm building a ros2 package based on [linorobot2](https://github.com/linorobot/linorobot2) which requires micro ros agent.

#### Behavior
Following the [installation tutorial](https://micro.ros.org/docs/tutorials/core/first_application_linux/), I execute the ```ros2 run build_agent.sh``` command and get this error:

#### Solutions tried:
-**Downgrading spdlog:** Jazzy's rclpy requires spdlog 1.15.0
-**Building libfmt from source** from [here](https://github.com/micro-ROS/micro-ROS-Agent/issues/50#issuecomment-2131215009) : Gives the above error as the new libfmt wasn't detected
-**Using the DUAGENT flag (both on/off)** from [here](https://github.com/micro-ROS/micro_ros_setup/issues/455#issuecomment-1042635375) : Still gives me the above error
-**Using the snap version** from [here](https://github.com/micro-ROS/micro-ROS-Agent/issues/186#issuecomment-1494091767) : The package does build successfully, however, the only micro-ros-agent package on snap was the foxy version, which causes fatal compatibility issues upon launching the linorobot2 package

It feels like I've tried everything short of a complete ros2/ubuntu reinstall (which I'd like to avoid, obviously). Does anyone has some advice?

首先使用 build_agent.sh 重现 Jazzy 构建，并检查第 63 行附近的 InterfaceLinux.hpp，因为 fmt/spdlog 错误在那里被实例化。跟踪构建选择了哪些 fmt 和 spdlog 安装，然后验证 micro-ROS Agent 能够成功构建，并且仍与报告中的 linorobot2 配置兼容。
