At this point, you will have the folder with the following files: $ ls

CMAKE COMMANDS CODE

Now, let build the source code with CMake. # Set the output folder where your program will be created test.cpp # include using namespace std Īnd you saved it as test.cpp, then to compile it in CMake you should create a txt file named CMakeLists.txt # Specify the minimum version for CMake CMake will do the job of Makefile from now. So I assume that you know C++ and what the Makefile is.

CMAKE COMMANDS INSTALL

To install CMake in Linux, just simply do on your terminal # For Ubuntu If you have some troubles with gcc and Makefile, just move out to CMake. In a short conclusion, CMake help you to manage and build your source codes effectively. This information is gathered into the cache, which may be changed by the user prior to the generation of the native build files. For example, when CMake runs, it locates include files, libraries, and executables, and may encounter optional build directives. Another nice feature of CMake is that it generates a cache file that is designed to be used with a graphical editor. CMake also supports static and dynamic library builds. CMake supports in-place and out-of-place builds, and can therefore support multiple builds from a single source tree. CMake can generate a native build environment that will compile source code, create libraries, generate wrappers and build executables in arbitrary combinations.

CMAKE COMMANDS WINDOWS

Simple configuration files placed in each source directory (called CMakeLists.txt files) are used to generate standard build files (e.g., makefiles on Unix and projects/workspaces in Windows MSVC) which are used in the usual way. Unlike many cross-platform systems, CMake is designed to be used in conjunction with the native build environment. What is CMake?ĬMake is an extensible, open-source system that manages the build process in an operating system and in a compiler-independent manner. The documentation states that SYMBOLIC property must be set for foo because the file does not exist but this didn’t make any difference.ĭependee messages are normal and generally harmless.Chapter 1: Let's start with CMake 1.

case 1: the header change doesn’t trigger a recompilation fixed by clearing the CMake cache.

add_custom_command(OUTPUT "foo" "$/date.h" The idea was to create a custom command with two OUTPUTs: the generated header file, which establishes a dependency (and precedence) with the related target (the “light”, automatic dependency is enough in this case), and a dummy one, which causes the command to always trigger. If DEPENDS is not specified, the command will run whenever the OUTPUT is missing if the command does not actually create the OUTPUT, the rule will always run. So, out of the three main options to define a custom command, as the book suggests, only add_custom_command meets the need. Targets are a big deal, they’re global, and need work and attention to be reliable. I need to generate a header with the current time at every build, and I really don’t want to define a custom target just to do that. I’m struggling to define a fixed pre-build command for a target.
