CMAKE Building Libraries Example

CMakeLists.txt

# Suppose a structure such as:
#... # root directory
#.../build
#.../lib
#.../lib/mylib.hpp
#.../lib/mylib.cc
#.../src
#.../src//main.cc
#.../CMakeLists.txt

#..... # your app .../src/main.cc
#include "../lib/mylib.hpp"
#..... # other things

# Once done with this file, navigate to build directory and run " cmake .. " as admin/root
# If everything goes well, you should get a Makefile in the build dir, then run " make " as admin/root
# You should get a main binary/executable in this build folder, run as admin/root 
 
# If you are looking for something more advanced... go to → https://github.com/TheBeachMaster/gtest
