CMake Error, Can't find Serial package configuration file

[Xpar65]

Hi. Whenever I try to build i get the error:
CMake Error at CMakeLists.txt:18 (find_package):
By not providing "Findserial.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "serial", but
CMake did not find one.

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

serialConfig.cmake
serial-config.cmake

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

I have tried:

• sudo apt install libserial-dev
• tried installing from source
• passing the directory of the build files using set(serial_DIR path path/to/serial/build)
• using the name depend>libserial-dev instead. Because: https://index.ros.org/d/libserial-dev/
• updating rosdeps.

Other notes:

• Im using humble
• all other packages are found

I am not sure how to fix this. My next option is trying to use another serial package instead. Any help would be much appreciated.

Yeah sorry, that's really not clear if you haven't got the tutorial that went with it!

The serial library is available here, however you probably want to be using the humble branch (main is foxy and I need to rename it and change the default), and that branch is using libserial-dev.
