How do I add several .cpp files into a single CMakeLists.txt

Question

I currently have a project with a template for one CMakeLists.txt for one executable, one header and one .cpp file. I would like for it to have several .cpp files, but still have it all compiled and build. How should I make the CMakeLists.txt file build and compile all the .cpp files, and how can I check if it worked?

How should I make the CMakeLists file build and compile all the .cpp files

add_executable in cmake accepts more than just one argument. So write your .cpp files as follows:

add_executable(my_project_executable main.cpp include/helper.cpp ...) 

Furthermore, using set is a basic practice for this, as follows:

set(SOURCES main.cpp include/helper.cpp ...)
add_executable(my_project_executable ${SOURCES}) 

how can I check if it worked?

Well, why don't you just build it to see if it works?

# See it build okay.
$ cmake .
$ make
