CMake print generator version (Make, Ninja, Visual Studio ...)

CMake print generator version

CMake doesn't print the generator version by default like it does with the compilers.

Usage:

cmake -Bbuild

switch generators like

cmake -Bbuild -G "Unix Makefiles" --fresh

-- Unix Makefiles /opt/homebrew/bin/gmake GNU Make 4.4.1

cmake -Bbuild -G Ninja --fresh

-- Ninja /opt/homebrew/bin/ninja 1.13.2

CMakeLists.txt

cmake_minimum_required(VERSION 3.20)

project(demoGen LANGUAGES CXX)

execute_process(COMMAND ${CMAKE_MAKE_PROGRAM} --version
OUTPUT_VARIABLE gen_ver)

string(REGEX REPLACE "\n" ";" gen_ver "${gen_ver}")

list(GET gen_ver 0 gen_ver)

message(STATUS "${CMAKE_GENERATOR}
${CMAKE_MAKE_PROGRAM}
${gen_ver}")
