The third option is to use a package manager tool, such as Windows Package Manager or Chocolatey. The second option is to download and build CMake from the source, and CMake even includes a source release download option. You just have to download the files and then walk through the interactive installation wizard. The first option is to use pre-compiled binaries as either the Windows Installer file (MSI) or the compressed version (ZIP) files. There are several ways to install CMake on Windows. It can separate the build system, intermediaries, and output files from the source code, keeping your code clean for the future. Developers using CMake can quickly check performance on different build backends and easily move between them.ĬMake can also help to keep your source code folder clean. When to Use CMakeĪs you can see, CMake can be a useful build system. It can be hard to find accurate information to resolve an issue or answer a question. This means your team can set a common policy regardless of what version people are using.Īnother disadvantage of CMake is the lack of information available for some versions. However, to help reduce this issue, CMake has introduced policies that define how certain CMake features should behave. While many would assume that CMake’s active development is an advantage (which it is!), it also has its downsides: Not everyone within a developer team will be running the same version of CMake. CMake can create a visualization of any dependencies within the project, that you can use to create documentation. It may be useful for some developers and software architects to understand what dependencies are within their projects and the nature of the dependency. CMake integration is supported by a variety of IDE tools, including CLion, Atom, and Visual Studio. A team can create a project using CMake, and then each developer can use their preferred IDE to work on it. Using CMake for projects, instead of something like Visual Studio projects, helps you avoid being locked into one integrated development environment (IDE). This means that a team of developers who are using different operating systems can still have common development tools. There are a number of benefits to using CMake to help build your solutions, including the fact that CMake can run on all major platforms, including Windows, Linux, and macOS. You’ll also walk through the process of installing it on Windows. In this article, you’ll learn more about CMake and if it’s the right solution for you. This gives developers the flexibility they need when building a new project and hopefully helps speed up the build. One of the main advantages of CMake is that it supports generating build scripts for a wide variety of platforms including Windows, macOS, and Linux. In the first version it will get expanded to your current working directory, while the second version will just pass the literal, unresolved string $PWD to CMake.CMake is an open source multiplatform tool that you can use to help with build automation, testing, packaging, and the installation of software. The reason your second version did not work for you is that you are using the $PWD variable from your shell, which CMake does not understand. For instance, a Windows shell will reject that command altogether. Note also that your first version is non-portable and specific to the shell you are using. Skipped if NO_CMAKE_ENVIRONMENT_PATH is passed. TheseĪre intended to be set in the user’s shell configuration. Search paths specified in cmake-specific environment variables. Intended to be used on the command line with a -DVAR=value. Search paths specified in cmake-specific cache variables. Note that we are talking about two different variables here, which are both named CMAKE_PREFIX_PATH. The second version is what you will want to use in most cases.Īs you have noticed, the first version sets the variable as a shell environment variable, while the second sets a CMake variable.
