c++ - How to build from multiple source files at once in Eclipse

Question

I have an Eclipse C++ project which initially has first.cpp. Then second.cpp is added and should be linked to the original file. Using Eclipse building tool, I got this output:

make all 
Building file: ../src/first.cpp
Invoking: GCC C++ Compiler
g++ -I/home/workspace/first/src -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/first.d" -MT"src/first.o" -o "src/first.o" "../src/first.cpp"
Finished building: ../src/first.cpp

Building file: ../src/second.cpp
Invoking: GCC C++ Compiler
g++ -I/home/workspace/first/src -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/second.d" -MT"src/second.o" -o "src/second.o" "../src/second.cpp"
Finished building: ../src/second.cpp

Building target: first
Invoking: GCC C++ Linker
g++ -L/usr/local/lib -o "first"  ./src/first.o ./src/second.o
Finished building target: first

How can I get Eclipse to compile this way?

g++ first.cpp second.cpp -o first

Thank you so much.

I am asking how to make a single binary from multiple source files, not building multiple binaries with multiple source files.

Try using CMake As per my understanding of your question, you would need to add your source files into CMakeList.txt and then run it. You can make use of this tutorial in doing so.
