The tools CMake provides are better than the ones Writing ModernĬMake reduces your chances of build problems. Somehow, this is difficult to understand, so I’ll shout it to make it clearer. Installing CMake can be as little as one line, and doesn’t require sudo

#CMAKE SET PRIVATE VARIABLE CODE#

Using a newer version canĬut your build system code in less than half, reduce bugs, integrate better with externalĭependents, and more. No one likes writing or debugging build systems.

#CMAKE SET PRIVATE VARIABLE UPGRADE#

Please, please upgrade andĭesign for newer CMake. Really old versions of CMake “available by default” in your environment. It was available in lots of Linux Distribution package managers.

You want to use tools, like Clang-Tidy, to help you codeĬMake has really changed dramatically since it was introduced around 2000.

You want to describe how your program is structured logically, not flags and commands.

You want to use an IDE, but maybe not all of the time.

You need to support different OSs (maybe even just flavors of Unix).

You want to use CI (continuous integration).

You need to build a package on more than one computer.

While it is nice to consolidate languages, the requirement that you haveĪn external language installed and configured was too high for any of these to catch on for general Note that both CMake and Make are custom languages rather than being built in an existing language, Like the CERN experiments being about to use it for thousands of modules. Well, with small projects able to pick it up easily (modern CMake, anyway), and massive projects But CMake has unparalleled support by IDEs, libraries, and compilers. (by Google), SCons (older Python system), Meson (young Python system, very opinionated), and a few Other BSGs include Autotools (old, inflexible), Bazel It is not really in the same category as make. The most popular BSG is CMake, which stands for Cross-platform Make. These usually write a build system (or IDE) file and then let that do the actuallyīuild. Of your programming language build they usually support common compilers, languages, libraries, and

Hard to extend if you want to use an IDE instead, good luck.Įnter Build System Generators (hereby labeled BSGs for brevity).

Not aware of dependencies: If you require a library, you have to handle the paths, etc.Platform/compiler dependent: You have to build the commands for each compiler.Mostly hand coded: You have to know all the proper commands.Generators), invoke (a Python one), and rake (Ruby make, nice syntax for Ruby users). Some common build systems include make (theĬlassic pervasive one), ninja (a newer one from Google designed in the age of build system These are language independent (mostly), allowing you to setup builds of almost anything youĬan use make to build LaTeX documents if you wish. To be built to build file B), and ways to store the commands used to build each file or type ofįile. So people came up with Build Systems these had ways set up dependencies (such as file A needs You need long commands to build each part of your code and you need do to Learn about build systems and build system generators.īuilding code is hard.
