Can't build agent because of fmt

Start by reproducing the Jazzy build with build_agent.sh and inspect InterfaceLinux.hpp around line 63, where the fmt/spdlog error is instantiated. Trace which fmt and spdlog installations the build selects, then verify that the micro-ROS Agent builds and remains compatible with the reported linorobot2 setup.

• 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 which requires micro ros agent.

Behavior

Following the installation tutorial, 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 : Gives the above error as the new libfmt wasn't detected
-Using the DUAGENT flag (both on/off) from here : Still gives me the above error
-Using the snap version from here : 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?
