Option(BUILD_SHARED_LIBS "Build shared library" ON)ĮXPORT_FILE_NAME $/cmake/yart-config-version. We would like the users to choose whether to build a shared library or a static one, 1 This line enables you to use yart::yart in the example target, will see late Configure the Target ) before, please be advised that you should explicitly list the source files like the example above for the build system to automatically reconfigure CMake when you add a new source file. You might have seen or have used file(GLOB. Without further ado, let’s set up our library first in src/CMakeLists.txt. An INTERFACE property means that a user will need to respect this property when depending on this target, while a PRIVATE property means that this property is only used internally. You’ll soon notice that many commands in CMake has a signature similar to command(your-target properties). Your library is a target, your executable is a target, and you’ll also meet some other types of targets when setting up the build system.Īnd each target has a set of properties attached to them, in an OO sense that they even have access control. Targets are the main objects CMake manipulate for building a project. The project command will create a YART project as well as versioning variables including YART_VERSION, YART_VERSION_MAJOR, YART_VERSION_MINOR and YART_VERSION_PATCH. Nothing interesting here, I’d like to use C++17 so CMake 3.10 is required. Let’s start with the parent level CMakeLists.txt. util.h // some internal utilities not intended for yart users main.cpp // an example program using yart Now suppose we are building a library yart, and the project is structured like bellow, 1 If you’d like to see a working example, you could try the code itself, there are only two external dependencies you need to install for it to work. The example code in this blog post is an simplified version of my project yart, stripping off the real files and 3rd-party dependencies. Basic knowledge of CMake is preferred, as I’ll not cover too much on some basic commands. Here I’ll present a detailed explaination on how to use modern CMake, especially for library developers who want to package their libraries for downstream developers to use easily with CMake. Although there are a few talks and tutorials about modern CMake on the Internet, I still find them hard to follow for the first time. But also like C++, CMake is a huge monster now which is very hard to tame. As opposed to the old ways of doing CMake like setting CMAKE_CXX_FLAGS directly, modern cmake introduces lots of facilities to handle dependencies more cleanly.
