- `buildRoot`: specifies the directory in which CMake generates build scripts for the chosen generator. Maps to **-DCMAKE_BINARY_DIR** switch and specifies where the CMake cache will be created. If the folder does not exist, it is created. Supported macros include `${workspaceRoot}`, `${workspaceHash}`, `${projectFile}`, `${projectDir}`, `${thisFile}`, `${thisFileDir}`, `${name}`, `${generator}`, and `${env.VARIABLE}`.

- `cacheRoot`: specifies the path to a CMake cache. This directory should contain an existing CMakeCache.txt file.

- `cmakeCommandArgs`: specifies additional command-line options passed to CMake when invoked to generate the cache.

- `configurationType`: specifies the build type configuration for the selected generator. May be one of:

- Debug

- Release

- MinSizeRel

- RelWithDebInfo

- `buildRoot`: specifies the directory in which CMake generates build scripts for the chosen generator. Maps to **-DCMAKE_BINARY_DIR** switch and specifies where the *CMakeCache.txt* will be created. If the folder does not exist, it is created.Supported macros include `${workspaceRoot}`, `${workspaceHash}`, `${projectFile}`, `${projectDir}`, `${thisFile}`, `${thisFileDir}`, `${name}`, `${generator}`, `${env.VARIABLE}`.

- `cmakeCommandArgs`: specifies additional command-line options passed to CMake when invoked to generate the project files.

- `cmakeToolchain`: specifies the toolchain file. This is passed to CMake using -DCMAKE_TOOLCHAIN_FILE."

- `buildCommandArgs`: specifies native build switches passed to CMake after --build --. For example, passing -v when using the Ninja generator forces Ninja to output command lines. See [Ninja command line arguments](#ninja) for more information on Ninja commands.

- `ctestCommandArgs`: specifies additional command-line options passed to CTest when running the tests."

- `codeAnalysisRuleset`: specifies the ruleset to use when running code analysis. This can be a full path or the file name of a ruleset file installed by Visual Studio.

- `installRoot`: specifies the directory in which CMake generates install targets for the chosen generator. Supported macros include `${workspaceRoot}`, `${workspaceHash}`, `${projectFile}`, `${projectDir}`, `${thisFile}`, `${thisFileDir}`, `${name}`, `${generator}`, `${env.VARIABLE}`.

- `cacheRoot`: specifies the path to a CMake cache. This directory should contain an existing *CMakeCache.txt* file.

|**$(WebDeployPath)**|The relative path from the web deployment root to where the project outputs belong. Returns the same value as <xref:Microsoft.VisualStudio.VCProjectEngine.VCWebDeploymentTool.RelativePath%2A>.|

The Universal C Run-Time Library (UCRT) supports most of the C standard library required for C++ conformance. It implements the C99 (ISO/IEC 9899:1999) library, with the exceptions of the type-generic macros defined in \<tgmath.h>, and strict type compatibility in \<complex.h>. The UCRT also implements a large subset of the POSIX.1 (ISO/IEC 9945-1:1996, the POSIX System Application Program Interface) C library, but is not fully conformant to any specific POSIX standard. In addition, the UCRT implements several Microsoft-specific functions and macros that are not part of a standard.

Functions specific to the Microsoft implementation of Visual C++ are found in the vcruntime library. Many of these functions are for internal use and cannot be called by user code. Some are documented for use in debugging and implementation compatibility.

The C++ standard reserves names that begin with an underscore in the global namespace to the implementation. Because the POSIX functions are in the global namespace, but are not part of the standard C runtime library, the Microsoft-specific implementations of these functions have a leading underscore. For portability, the UCRT also supports the default names, but the Microsoft C++ compiler issues a deprecation warning when code that uses them is compiled. Only the default POSIX names are deprecated, not the functions. To suppress the warning, define `_CRT_NONSTDC_NO_WARNINGS` before including any headers in code that uses the original POSIX names.

Certain functions in the standard C library have a history of unsafe usage, because of misused parameters and unchecked buffers. These functions are often the source of security issues in code. Microsoft created a set of safer versions of these functions that verify parameter usage and invoke the invalid parameter handler when an issue is detected at runtime. By default, the Microsoft C++ compiler issues a deprecation warning when a function is used that has a safer variant available. When you compile your code as C++ , you can define `_CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES` as 1 to eliminate most warnings. This uses template overloads to call the safer variants while maintaining portable source code. To suppress the warning, define `_CRT_SECURE_NO_WARNINGS` before including any headers in code that uses these functions. For more information, see [Security Features in the CRT](../c-runtime-library/security-features-in-the-crt.md).

Except as noted within the documentation for specific functions, the UCRT is compatible with the Windows API. Certain functions are not supported in Windows 8 Store apps or in Universal Windows Platform (UWP) apps on Windows 10. These functions are listed in [CRT functions not supported in Universal Windows Platform apps](../cppcx/crt-functions-not-supported-in-universal-windows-platform-apps.md), which enumerates the functions not supported by the Windows Runtime and [UWP](/uwp).
