Making my first custom app

#1

I am trying to make my first custom app to run in flytsim using the link:http://docs.flytbase.com/docs/FlytOS/Developers/BuildingCustomApps/OnboardCPP.html#write-onboard-cpp

But while following the steps for building the file:(Using Cmake … command)
I get this error:

CMake Error at CMakeLists.txt:9 (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.

– Configuring incomplete, errors occurred!
