In my opinion the best reference is a combination of looking at examples online especially in kitware libraries and also using the built-in help cmake —help along with subscribing to the mailing list. However, I really wish they had put the text of this book online instead of making people buy it. Michael marked it as to-read Oct 15, Feb 17, Mohammed Moh added it.

Installing and Testing Step 3 Adding a Generated File and Generator Step 5 If you have ever maintained the build and installation process for a software package, you will be interested in CMake. CMake is an open source build manager for software projects that allows developers to specify build parameters in a simple portable text file format.

CMake handles the difficult aspects of building software such as cross platform builds, system introspection, and user customized builds, in a simple manner that allows users to easily tailor builds for complex hardware and software systems. For any project, and especially cross platform projects, there is a need for a unified build system. This requires that developers constantly try to keep both build systems up to date and consistent with each other. To target additional build systems.

This problem is compounded if you try to support optional components, such as including JPEG support if libjpeg is available on the system. CMake solves this by consolidating these different operations into one simple easy to understand file format. If you have multiple developers working on a project, or multiple target platforms, then the software will have to be built on more than one computer. Given the wide range of installed software and custom options that are involved with setting up a modern computer, the chances are that two computers running the same OS will be slightly different.

CMake provides many benefits for single platform multi-machine development environments including: 2 Why CMake? This allows a developer to remove an entire build directory without fear of removing source files. These commands are used to generate new source files during the build process that are in turn compiled into the software.

CMake knows how to create shared libraries and modules on all platforms supported. Complicated platform- specific linker flags are handled, and advanced features like built in run time search paths for shared libraries are supported on many UNIX systems.

This avoids the problem of developers having to maintain the same information in several different formats inside a project. CMake can create header files that contain information such as paths to data files and other information in the form of define macros. System specific flags can also be placed in configured header files. The History of CMake 3 1. ITK is a large software project that works on many platforms and can interact with many other software packages.

To support this, a powerful, yet easy to use, build tool was required. Having worked with build systems for large projects in the past, the developers designed CMake to address these needs. Since then CMake has continuously grown in popularity, with many projects and developers adopting it for its ease of use and flexibility. Since CMake has been under active development and has matured to the point where it is a proven solution for a wide range of build issues.

The most telling example of this is the successful adoption of CMake as the build system of the K Desktop Environment KDE , arguably the largest open source software project in existence. One of the recent additions to CMake is the inclusion of software testing support in the form of CTest.

Part of the process of testing sofiware involves building the software, possibly installing it, and determining what parts of the sofiware are appropriate for the current system. This makes CTest a logical extension of CMake as it already has most of this information.

In a similar vein, a new CMake feature is CPack, which is designed to support cross platform distribution of sofiware. With CMake, once you write your input files you get support for new compilers and build systems for free because the support for them is built into new releases of CMake, not tied to your software distribution.

Another recent addition to CMake is support for cross compiling to other operating systems or embedded devices. Many commands in CMake now properly handle the differences between the host system and the target platform when cross compiling. Before developing CMake its authors had experience with the existing set of available tools.

Autoconf combined with automake provides some of the same functionality as CMake, but to use these tools on a Windows platform requires the installation of many additional tools not found natively on a Windows box. In addition to requiring a host of tools, autoconf can be difficult to use or extend and impossible for some tasks that are easy in CMake.

Even if you do get autoconf and its required environment running on your system, it generates Makefiles that will force users to the command line. CMake on the other hand provides a choice, allowing developers to generate project files that can be used directly from the IDE to which Windows and Xcode developers are accustomed. For example.

CMake provides an interactive user interface, making it easy for the user to see what options are available and how to set them For UNIX users, CMake also provides automated dependency generation that is not done directly by autoconf.

Of the four, qmake, is the most similar to CMake although it lacks much of the system interrogation that CMake provides. Many of these tools require other tools such as Python or Java to be installed before they will work.

Why Not Script It Yourself? Some projects use existing scripting languages such as Perl or Python to configure build processes. Although similar functionality can be achieved with systems like this, over-use of tools can make the build process more of an Easter egg hunt than a simple-to-use build system. When building your software package users are forced to find and install version 4.

To avoid that problem, it was decided that CMake would require no more tools than the software it was being used to build would require. Scripting it yourself also typically means you will not be generating native Xcode or Visual Studio workspaces, making Mac and Windows builds limited. You can check www. Likewise, CMake supports most common compilers. If the compiler takes arguments in a strange way, then see the section Porting CMake to New Platform on page for information on how to customize CMake for a new compiler.

Chapter 2 Getting Started 2. On many systems you may find that CMake is already installed, or is available for install with the standard package manager tool for the system.

If your system does not have a CMake package, you can find CMake precompiled for most commen architectures at www. If you do not find binaries for your system precompiled, then you can build CMake from source.

If your system does not have CMake, or has an out of date version of CMake, you can download precompiled binaries from www. The binaries from www. However, it can be any directory, and does not require root privileges for installation. You will be able to run CMake from the Start Menu after it is installed. Once you have the source code it can be built in two different ways. If you have a version of CMake on your system you can use it to build other versions of CMake.

Generally the current development version of CMake can always be built from the previous release of CMake. This is how new versions of CMake are built on most Windows systems. The second way to build CMake is by running its bootstrap build script. To do this you change directory into your CMake source directory and type. This is done by setting the environment variable Cxx before sunning bootstrap. For example, on the SGI with the 7. The language is expressed as a series of commands.

Bach command is evaluated in the order that it appears in the CMakeLists file. The commands. Hello World for CMake 9 where command is the name of the command, and args is a white-space separated list of arguments. Arguments with embedded white-space should be double quoted. CMake is case insensitive to command names as of version 2. Older versions of CMake only accepted uppercase commands. CMake supports simple variables that can be either strings or lists of strings.

Multiple arguments can be grouped together into a list using the set command. All other commands expand the lists as if they had been passed into the command with white-space separation. If you want to pass a list of arguments to a command as if it were a single argument simply double quote it. Consider the more complicated example below. The if command is used to add either WinSupport.

Note the use of the character to denote a comment line. All characters from the ta the end of the line are considered to be part of the comment. Once CMake has been installed on your system, using it to build a project is easy.

There are two main directories CMake uses when building a project: the source directory and the binary directory. The source directory is where the source code for your project is located. This is also where the CMakeLists files will be found. The binary directory is where you want CMake to put the resulting object files, libraries, and executables. Typically CMake will not write any files to the source directory, only the binary directory.

If you want to you can set the source and binary directories to be the same. This is known as an in-source build, in contrast to an out-of-source build where they are different. How to Run CMake?

This means that you can configure your build to be completely outside of the source code tree which makes it very easy to remove all of the files generated by a build. Having the build tree differ from the source tree also makes it easy to support having multiple builds of a single source tree.

This is useful when you want to have multiple builds with different options but just one copy of the source code. This interface is included in the CMake source code, but you will need an installation of Qt on your system in order to build it.

Generate Current Generator: Visual Studio 9 Searching 16 bit integer Check size of unsigned short Check size of unsigned short - done Using unsigned short Check if the system is big endian - little endian Locking for elf. There may also be a shortcut on your desktop, or if you built CMake from source, it will be in the build directory. A GUI will appear similar to what is shown in Figure.
