#CMAKE ADD EXECUTABLE HOW TO#

This file contains all the compilation rules for our library. Moreover, CMake is open source and is available on almost all platforms.įor these reasons, since version 0 of our C++ library, we added a CMakeLists.txt file in the Sources subdirectory. Because of that, build system, such as CMake, doesn't have to know about them when the final. cc) which has include directive to include the file.

As we are going to see below, the CMake syntax is much simpler, making the life of the developer easier as well. hpp extension, although not always - for example, C++ standard library headers have no extensions - are 'copy-pasted' by compiler into every. when CMake runs, it locates include files, libraries, and executables. cpp file into an executable, but its syntax is very complex and becomes almost incomprehensible for large projects. CMake can generate a native build environment that will compile source code. Indeed, GNU make already enables us to describe the commands to be run to transform a.

(The source files can be omitted here if they are added later using targetsources().) The corresponds to the. ) Adds an executable target called to be built from the source files listed in the command invocation. addexecutable( WIN32 MACOSXBUNDLE EXCLUDEFROMALL source1 source2.

We could wonder why not using GNU make directly. addexecutable Add an executable to the project using the specified source files. Usually under Linux, one uses CMake to generate a GNU make file which then uses gcc or g++ to compile the source file and to create the executable.ĬMake generates makefiles which enable you to compile the application with gccĪ CMake project is composed of source files and of one or several CMakeLists.txt files containing the required information to compile the application, such as the location of the source files, the name of the executable, the libraries to be used, and so on. In other words, the role of CMake is not to actually build the executable, but to prepare a list of commands to be performed to generate the executable. Notice that gflags is a CMake project, so you can add it as a. You can add paths to other CMake executables and use them in different build. CMake is neither a compiler nor an IDE, but it is a 'tool for managing the build process of software'. When you create an executable, youll need to link individual object files or libraries. Qt Creator automatically detects the CMake executable specified in the PATH.

If it is not the case, we recommend that you start by reading our post ' How to start in C++ with Yoctopuce modules' which explains how our library works.įirst of all, a few words on CMake. Note: we assume that you already have a minimal knowledge of the C++ language and of our programming libraries. However, we hadn't yet documented how to use CMake to compile the library and use it in a program. This process is documented in the README file and there is a post explaining how to compile the library with the Code::Blocks IDE. Recently, we have had several customers who decided to compile our C++ library under Linux.
