Consider this b2 project:

# jamroot.jam
exe main : main.cpp ;

In order to build it in debug and release I would call b2 like this:

b2 variant=debug,release

With a similar CMake project:

#CMakeLists.txt
cmake_minimum_required(VERSION 3.5)
project(proj LANGUAGES CXX)
add_executable(main main.cpp)

Building debug and release (using a single config generator) is done with e.g.
cmake -S. -Bbuild/debug -DCMAKE_BUILD_TYPE=Debug
cmake --build build/debug
cmake -S. -Bbuild/release -DCMAKE_BUILD_TYPE=Release
cmake --build build/release

Neither b2 nor CMake requires any changes to build scripts to build
different configurations.
