USING CMAKE LINUX HOW TO
USING CMAKE LINUX INSTALL
USING CMAKE LINUX CODE

For example, in case of MacPorts, typing the following sudo port install cmake On Mac OSX, if you use one of the package managers available to install your software, the most notable being MacPorts ( MacPorts) and Homebrew ( Homebrew), you could also install CMake via one of them. On FreeBSD you can install the command-line and the Qt-based graphical application with: pkg install cmake On Ubuntu 16.04 you can install the command-line and graphical application with: sudo apt-get install cmake

On Linux, you can also install the packages from the distribution's package manager. On Windows double click the binary to install.

Head over to CMake download page and get a binary for your operating system, e.g. "Hello World" with multiple source filesįirst we can specify the directories of header files by include_directories(), then we need to specify the corresponding source files of the target executable by add_executable(), and be sure there's exactly one main() function in the source files.įollowing is a simple example, all the files are assumed placed in the directory PROJECT_SOURCE_DIR. Include_directories($)Īnd following the same steps, we'll get the same result. We modify CMakeLists.txt to cmake_minimum_required(VERSION 2.4) Instead of building from multiple source files, we can first deploy foo.cpp as a library by using add_library() and afterwards linking it with the main program with target_link_libraries(). Say we have the same set of source/header files as in the example.

USING CMAKE LINUX HOW TO

This example shows how to deploy the "Hello World" program as a library and how to link it with other targets. Each only handles as much of the build as is present in the current directory.įor official resources on CMake, see CMake's Documentation and Tutorial. The final CMakeLists files can be very clear and straightforward, because each is so limited in scope.

Locate a library which is somewhere in the source tree.

Generate a file, based on the specific build configuration.

Define variables that the buildsystem will use in this directory, and in its subdirectories.

Add a filepath to the include-path used during build.

Build a library or an executable out of some of the source files in this directory.

It also defines which subdirectories CMake should handle as well. Each directory's CMakeLists file defines what the buildsystem should do in that specific directory. On Linux, CMake generates Makefiles on Windows, it can generate Visual Studio projects, and so on.īuild behavior is defined in CMakeLists.txt files - one in every directory of the source code. It accomplishes this by pairing with different platform-specific buildsystems CMake is an intermediate step, that generates build input for different specific platforms.

USING CMAKE LINUX CODE

CMake is a tool for defining and managing code builds, primarily for C++.ĬMake is a cross-platform tool the idea is to have a single definition of how the project is built - which translates into specific build definitions for any supported platform.
