Cmake compile targets

add_executable

Compiles a single executable file.

add_executable(
    compiled_program
    source.cpp
    lib/source2.cpp
    lib/source3.cpp
)

If it were run on the commandline, this might translate to something like:

g++      source.cpp lib/source2.cpp lib/sourc3.cpp  -o compiled_program  # using compiler 'gcc'
clang++  source.cpp lib/source2.cpp lib/sourc3.cpp  -o compiled_program  # using compiler 'clang'
 
# something entirely different for VScode, eclipse, ... etc...
