CMake creates huge binary when I incude a standard library

I've just created an Helloworld in C++ using Cmake. Output binary is, as expected, 10KB. When I add #include <string> in main without using any strings, the generated binary turn to 100KB.

When I manually compile same main.cpp file gcc main.cpp -o helloworld, the output binary has same size, with or without #include <string>

Is there any Cmake keyword to use in order to allow the output binary includes everything dynamically, instead of having all libraries internally?

Solution

  • I've got the problem. In my CMakeLists.txt file was present

    add_compile_options(-Wall -Werror -std=c++17 -g)

    So

    -DCMAKE_BUILD_TYPE=Release

    did not have any effect.

    I just removed -g parameter and Debug symbols simply disappear from output binary
