## # vcpkg_build_msbuild
##
## Build an msbuild-based project.
##
## ## Usage
## ```cmake
## vcpkg_build_msbuild(
##     PROJECT_PATH <${SOURCE_PATH}/port.sln>
##     [RELEASE_CONFIGURATION <Release>]
##     [DEBUG_CONFIGURATION <Debug>]
##     [TARGET <Build>]
##     [TARGET_PLATFORM_VERSION <10.0.15063.0>]
##     [PLATFORM <${TRIPLET_SYSTEM_ARCH}>]
##     [PLATFORM_TOOLSET <${VCPKG_PLATFORM_TOOLSET}>]
##     [OPTIONS </p:ZLIB_INCLUDE_PATH=X>...]
##     [OPTIONS_RELEASE </p:ZLIB_LIB=X>...]
##     [OPTIONS_DEBUG </p:ZLIB_LIB=X>...]
## )
## ```
##
## ## Parameters
## ### USE_VCPKG_INTEGRATION
## Apply the normal `integrate install` integration for building the project.
##
## By default, projects built with this command will not automatically link libraries or have header paths set.
##
## ### PROJECT_PATH
## The path to the solution (`.sln`) or project (`.vcxproj`) file.
##
## ### RELEASE_CONFIGURATION
## The configuration (``/p:Configuration`` msbuild parameter) used for Release builds.
##
## ### DEBUG_CONFIGURATION
## The configuration (``/p:Configuration`` msbuild parameter)
## used for Debug builds.
##
## ### TARGET_PLATFORM_VERSION
## The WindowsTargetPlatformVersion (``/p:WindowsTargetPlatformVersion`` msbuild parameter)
##
## ### TARGET
## The MSBuild target to build. (``/t:<TARGET>``)
##
## ### PLATFORM
## The platform (``/p:Platform`` msbuild parameter) used for the build.
##
## ### PLATFORM_TOOLSET
## The platform toolset (``/p:PlatformToolset`` msbuild parameter) used for the build.
##
## ### OPTIONS
## Additional options passed to msbuild for all builds.
##
## ### OPTIONS_RELEASE
## Additional options passed to msbuild for Release builds. These are in addition to `OPTIONS`.
##
## ### OPTIONS_DEBUG
## Additional options passed to msbuild for Debug builds. These are in addition to `OPTIONS`.
