![]() ![]() ![]() The advantages of using CMake should not be understated. The buildsystem is the thing that understands (because you instruct it on) how your project needs to be built- what source files it has, and how those source files should get compiled into object files, and how those object files should get linked together into executables or dynamic/shared or static libraries. Such supported buildsystems include (but are not limited to): Ninja, Unix Makefiles, Visual Studio solutions, and XCode. You give the CMake program that configuration and tell it what kind of buildsystem to generate, and it generates it ( providing that that buildsystem is supported). You write a configuration to describe a buildsystem (a project and its build targets and how they should be built) (and optionally, tested, installed, and packaged). Every time I think that I am getting closer to understanding how CMake is meant to be written, it vanishes in the next example I read.ĬMake is a buildsystem generator. Somehow I am totally confused by how CMake works. ![]() Trust me- this answer could have been a lot longer than it is. Note: This answer is long because the innocent-looking question and the multiple topics it covers are deceptively broad, and the question's intended audience is for beginners (people new to CMake). String resourcePath = string(RESOURCE_PATH) + "file.png" With this variable set foobar($")įinally, where you need the path in your code, you can do: #include "configuration.h" You can set lists/variables with set(args arg1 arg2). foobar(3.0) and foobar("3.0") is the same. The basic rule to understand CMake commands is the following syntax: Therefore resources are loaded relative to the executable. I wanted to have a simple zip/tar.gz file that you can extract anywhere and run. By default CMake wants to put them in /usr/share/, /usr/local/share/ and something equivalent on Windows. One thing it does non-standard is resource handling. Here it is, and it tries to cover most of the basics, including resources and packaging. After some research, I have now my own version of the most simple but complete CMake example. ![]()
