Provides the add_module_library
CMake function that is a wrapper around add_library
with additional module-specific rules. Currently supports clang 15+ and gcc 12+ and can fallback to a non-modular library for compatibility.
Projects using add_module_library
:
- {fmt}: a modern formatting library
hello.cc
:
module;
#include <cstdio>
export module hello;
export void hello() { std::printf("Hello, modules!\n"); }
main.cc
:
import hello;
int main() { hello(); }
CMakeLists.txt
:
cmake_minimum_required(VERSION 3.11)
project(HELLO CXX)
include(modules.cmake)
add_module_library(hello hello.cc)
add_executable(main main.cc)
target_link_libraries(main hello)
Building with clang:
CXX=clang++ cmake .
make
Running:
$ ./main
Hello, modules!
