## # 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.
##
## ### ADD_BIN_TO_PATH
## Adds the appropriate Release and Debug `bin\` directories to the path during the build such that executables can run against the in-tree DLLs.
##
## ## 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)
## * [poco](https://github.com/Microsoft/vcpkg/blob/master/ports/poco/portfile.cmake)
## * [opencv](https://github.com/Microsoft/vcpkg/blob/master/ports/opencv/portfile.cmake)
