We\u2019ve introduced a bunch of improvements to our CMake support in the latest preview of Visual Studio 2019 Update 1<\/a>. The latest release includes Clang\/LLVM support, CMake 3.14, better vcpkg<\/a> integration, and many more enhancements. If you are not familiar with Visual Studio\u2019s CMake support, check out how to get started<\/a>.<\/p>\n

Clang\/LLVM Support<\/h3>\n

Visual Studio now supports Clang\/LLVM for CMake projects and you can now use Clang to target Windows and remote Linux machines. Full IntelliSense is supported along with Visual Studio\u2019s comprehensive debugging support. Check out our Clang\/LLVM post<\/a> for much more information.<\/p>\n

CMake 3.14 with Performance Improvements and Visual Studio 2019 Generator<\/h3>\n

We\u2019ve updated the version of CMake that ships with Visual Studio to 3.14. This version includes the latest MSBuild generators that support Visual Studio 2019. You can learn more about what’s new in CMake 3.14<\/a> in CMake\u2019s release notes.<\/p>\n

Microsoft also worked with the CMake community to bring a new way of interfacing IDEs with CMake in 3.14 that replaces CMake server mode. What this means for you, is that many CMake operations (especially configuration) will be faster from now on. If you are interested in learning more about this, we are going to be writing a whole post about this soon.<\/p>\n

Better Vcpkg Integration<\/h3>\n

In our first release of Visual Studio 2019 we introduced basic integration with vcpkg<\/a>. In the latest preview we have enhanced with better integration with IntelliSense. Now, when you are adding a header for a missing library, we will recommend how to install it with vcpkg if it is available. There is also now IntelliSense for CMake\u2019s \u201cfind_package\u201d directive:<\/p>\n

Simpler CMake Build and Install Roots<\/h3>\n

With Visual Studio 2019 version 16.1 Preview 2 we have updated the default build and install roots for local and remote CMake projects to be more in-line with the standard set by open-source CMake projects. When you create a new CMake project in Visual Studio using the \u201cCMake Project\u201d template, or add a new configuration to an existing project, the following build and install roots will be used. You can change these properties at any time by modifying the \u201cBuild root\u201d and \u201cInstall root\u201d (or \u201cRemote build root\u201d and \u201cRemote install root\u201d) properties of the CMake Settings Editor<\/a>.<\/p>\n

Local CMake Projects:<\/strong><\/p>\n

Build root: ${projectDir}\\\\out\\\\build\\\\${name}\nInstall root: ${projectDir}\\\\out\\\\install\\\\${name}<\/p>\n

Remote CMake Projects:<\/strong><\/p>\n

Remote build root: $HOME\/.vs\/${projectDirName}\/${workspaceHash}\/out\/build\/${name}\nRemote install root: $HOME\/.vs\/${projectDirName}\/${workspaceHash}\/out\/install\/${name}<\/p>\n
