I have 4 separate packages:
I saved them in a master folder and tried compiling them using catkin_make and got the following cmake error: CMake Error at devel/share/glog_catkin/cmake/glog_catkinConfig.cmake:148 (message):
Project 'msf_core' tried to find library 'glog'. The library is neither a
target nor built/installed properly. Did you compile project
'glog_catkin'? Did you find_package() it before the subdirectory containing
its code is included?

Invoking "cmake" failed
So I tried compiling them individually. After compiling one of them and trying to compile the others, I got the following error:
CMake Error: The source "/home/yukti/Desktop/MSF_PACKAGE/asctec_mav_framework-master/CMakeLists.txt" does not match the source "/home/yukti/Desktop/MSF_PACKAGE/catkin_simple-master/CMakeLists.txt" used to generate cache. Re-run cmake with a different source directory.
Invoking "cmake" failed
Another thing I tried was creating multiple folders that individually stored each package and compiling them. I still failed to make it work.
I am having trouble determining if I need to create multiple catkin workspaces or try overlaying them or if there is a simpler solution to the problem.
Thanks for the help!
Placing multiple packages inside a workspace is possible and a fundamental approach in ROS.
The error
Project 'msf_core' tried to find library 'glog'.
tells that the glog library is needed to compile but missing. Check out How to install and use GLog and install glog like
sudo apt install libgoogle-glog-dev
After installing the library compilation should be possible.
