Set(MY_LIBRARY_VERSION_MAJOR 1 CACHE STRING "major version" FORCE) # define library version (update: apparently you can also do it in project()!) The root CMakeLists.txt can look as follows: cmake_minimum_required(VERSION 3.0) This allows a seperation of CMake’s config files and other, unrelated configuration macros etc. The configurations will be set in the file which will be preprocessed to config_impl.hpp and included by config.hpp. The root CMakeLists.txt defines configuration options and adds the subdirectories. The library, the examples and the tool each has their own CMakeLists.txt defining the target and related code in their subdirectory. It also comes with some examples, a tool and unit tests. So we have a library consisting of various header and source files. The setupįor the scope of the tutorial, let’s say we have a library that has the following CMake structure: - include/
Throughout this post, I’ll be assuming a 3.x CMake version and an already existing CMake project. In particular, the system will be able to handle multiple installed versions and multiple configurations.
In this post, I will show you how to install your library so that it can be used easily by other projects. As of version 0.5 my memory library now provides support for system-wide installation and CMake’s find_package().īecause I’ve spent hours of trial and error to come up with it, I’ll document it here.
