OSX Install Issue

[79rpm]

Hello,

I am in the process of installing the serial library on x86 so I can do some emulation for an embedded project I have. I am having issues installing catkin properly, would you please let me know what to do?

I am running an older version of OSX 10.12.6. I have followed the description here:
https://docs.ros.org/en/api/catkin/html/user_guide/installation.html#prerequisites

I issued the following command and my terminal:

$ pip install -U catkin_pkg
Requirement already satisfied: catkin_pkg in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (0.4.23)
Requirement already satisfied: pyparsing in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from catkin_pkg) (2.4.7)
Requirement already satisfied: docutils in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from catkin_pkg) (0.17.1)
Requirement already satisfied: python-dateutil in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from catkin_pkg) (2.8.2)
Requirement already satisfied: six>=1.5 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (from python-dateutil->catkin_pkg) (1.16.0)

If I call cmake from the serial directory I get the following:

$ cmake ..
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.

Update the VERSION argument value or use a ... suffix to tell
CMake that the project does not need compatibility with older versions.

CMake Error at CMakeLists.txt:5 (find_package):
By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "catkin", but
CMake did not find one.

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

catkinConfig.cmake
catkin-config.cmake

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

What am I missing?

I doubt if you're still working on this, but I had the same problem and fixed it this way:
Run sudo find / -type f | grep "catkinConfig.cmake" (I use Linux, you'll probably have to modify this command), and once it's done run this: export CMAKE_PREFIX_PATH="$CMAKE_PREFIX_PATH:<the directory (/opt/ros/noetic/share/catkin/cmake in my case)>". I hope this helped!
