+## # vcpkg_build_cmake
+##
+## Build a cmake project.
+##
+## ## Usage:
+## ```cmake
+## vcpkg_build_cmake([DISABLE_PARALLEL] [TARGET <target>])
+## ```
+##
+## ## Parameters:
+## ### DISABLE_PARALLEL
+## The underlying buildsystem will be instructed to not parallelize
+##
+## ### TARGET
+## The target passed to the cmake build command (`cmake --build . --target <target>`). If not specified, no target will
+## be passed.
+##
+## ## Notes:
+## This command should be preceeded by a call to [`vcpkg_configure_cmake()`](vcpkg_configure_cmake.md).
+## You can use the alias [`vcpkg_install_cmake()`](vcpkg_configure_cmake.md) function if your CMake script supports the
+## "install" target
+##
+## ## Examples:
+##
+## * [zlib](https://github.com/Microsoft/vcpkg/blob/master/ports/zlib/portfile.cmake)
+## * [cpprestsdk](https://github.com/Microsoft/vcpkg/blob/master/ports/cpprestsdk/portfile.cmake)

 ## ## Usage:

 ## ## Parameters:
-## ### MSVC_64_TOOLSET
-## This adds the `/p:PreferredToolArchitecture=x64` switch if the underlying buildsystem is MSBuild. Some large projects can run out of memory when linking if they use the 32-bit hosted tools.
+## See [`vcpkg_build_cmake()`](vcpkg_build_cmake.md).

 ## ## Notes:
-## This command should be preceeded by a call to [`vcpkg_configure_cmake()`](vcpkg_configure_cmake.md).
+## This command transparently forwards to [`vcpkg_build_cmake()`](vcpkg_build_cmake.md), adding a `TARGET install`
+## parameter.
