Std::cout << "Hello, World!" << std::endl In our “main.cpp” file we will write down the following “Hello, World!” application: #include We will have the following project structure: root cpp file to demonstrate how CMake will generate a project and compile that file. We will start as always with our “Hello, World!” application using a single. We will have the most simple example for our first compile using CMake. The install wizard is pretty straightforward just make sure that on the question “By default CMake does not add its directory to the system PATH” you check one of the options Add CMake to system Path so that later we can execute commands from the windows terminal. It should roughly look something like this: You should find the corresponding binary for your windows installation (圆4, x86) and download the. Read more: You can check out more on how the compiler and linker work to gain in depth knowledge on why the process is different than other languages. This essentially means that we unify our project files under CMake which on the other hand generates the project files for the specific system. ![]() On Windows one would want to work with Visual Studio project files and solutions and on Linux one would rather have Make files. This is what CMake strives to solve but the other way around. ![]() That code is then run by a special virtual machine that translates it to commands for the specific machine. On other languages like Java, C# and python the code is always compiled to an intermediate language or is interpreted directly at runtime. When programming in C++ it is hard to target multiple platforms as there is no unified project structure as well as good package management. As an old language though it misses some of the modern high-level language concepts. Do not make a mistake it is really powerful and provides a lot of control over low level memory and system programming. CMake will automatically detect your Visual Studio installation later.Ĭ++ is an old language.
