Vcpkg helps you get C and C++ libraries on Windows.
For short description of available commands, run vcpkg help.
First, we need to know what name C++ REST SDK goes by in the ports tree. To do that, we'll run the search command and inspect the output:

Looking at the list, we can see that the port is named "cpprestsdk".
Installing is then as simple as using the install command. Since we haven't built this library before, we'll first see an error message indicating that the control file failed to load, then the port will automatically begin building (and install when completed).

Package cpprestsdk:x86-windows is installed
In addition to installing, vcpkg caches a pristine copy of the built library inside the packages\ directory (in this case, packages\cpprestsdk_x86-windows). This allows you to quickly uninstall and reinstall the library in the future using the remove and install commands.
We can check that cpprestsdk was successfully installed for x86 windows desktop by running the list command.
PS D:\src\vcpkg> .\vcpkg list
cpprestsdk:x86-windows 2.8 A modern C++11 library to connect with web servic...
To install for other architectures and platforms such as Universal Windows Platform or x64 Desktop, you can suffix the package name with :<target>.
PS D:\src\vcpkg> .\vcpkg install cpprestsdk:x86-uwp zlib:x64-windows
See vcpkg help triplet for all supported targets.
The recommended and most productive way to use vcpkg is via user-wide integration, making the system available for all projects you build. The user-wide integration will require administrator access the first time it is used on a given machine. After the first use, administrator access is no longer required and the integration is on a per-user basis.
PS D:\src\vcpkg> .\vcpkg integrate install
Applied user-wide integration for this vcpkg root.
All C++ projects can now #include any installed libraries.
Linking will be handled automatically.
Installing new libraries will make them instantly available.
Note: You will need to restart Visual Studio or perform a Build to update intellisense with the changes.
To remove the integration for your user, you can use vcpkg integrate remove.
The best way to use installed libraries with cmake is via the toolchain file scripts\buildsystems\vcpkg.cmake. To use this file, you simply need to add it onto your CMake command line as -DCMAKE_TOOLCHAIN_FILE=D:\src\vcpkg\scripts\buildsystems\vcpkg.cmake.
Let's first make a simple CMake project with a main file.
# CMakeLists.txt
cmake_minimum_required(VERSION 3.0)
project(test)
find_library(CPPREST_LIBRARY cpprest_2_8)
find_path(CPPREST_INCLUDE_DIR cpprest/version.h)
include_directories(${CPPREST_INCLUDE_DIR})
link_libraries(${CPPREST_LIBRARY})
add_executable(main main.cpp)// main.cpp
#include <cpprest/json.h>
#include <stdio.h>
int main()
{
auto v = web::json::value::parse(U("[1,2,3,4]"));
printf("Success\n");
return 0;
}Then, we build our project in the normal CMake way:
PS D:\src\cmake-test> mkdir build
PS D:\src\cmake-test> cd build
PS D:\src\cmake-test\build> cmake .. "-DCMAKE_TOOLCHAIN_FILE=D:\src\vcpkg\scripts\buildsystems\vcpkg.cmake"
// omitted CMake output here //
-- Build files have been written to: D:/src/cmake-test/build
PS D:\src\cmake-test\build> cmake --build .
// omitted MSBuild output here //
Build succeeded.

Libraries are installed into the installed\ subfolder, partitioned by architecture (e.g. x86-windows):
- The header files are installed to
installed\x86-windows\include - Release
.libfiles are installed toinstalled\x86-windows\lib - Release
.dllfiles are installed toinstalled\x86-windows\bin - Debug
.libfiles are installed toinstalled\x86-windows\debug\lib - Debug
.dllfiles are installed toinstalled\x86-windows\debug\bin
See your build system specific documentation for how to use prebuilt binaries.
Generally, to run any produced executables you will also need to either copy the needed dll files to the same folder as your exe or prepend the correct bin directory to your path.
Example for setting the path for debug mode in powershell:
PS D:\src\vcpkg> $env:path = "D:\src\vcpkg\installed\x86-windows\debug\bin;" + $env:path
We also provide individual VS project integration through a NuGet package. This will modify the project file, so we do not recommend this approach for open source projects.
PS D:\src\vcpkg> .\vcpkg integrate project
Created nupkg: D:\src\vcpkg\scripts\buildsystems\vcpkg.D.src.vcpkg.1.0.0.nupkg
With a project open, go to Tools->NuGet Package Manager->Package Manager Console and paste:
Install-Package vcpkg.D.src.vcpkg -Source "D:/src/vcpkg/scripts/buildsystems"
Note: The generated NuGet package does not contain the actual libraries. It instead acts like a shortcut (or symlink) to the vcpkg install and will "automatically" update with any changes (install/remove) to the libraries. You do not need to regenerate or update the NuGet package.
First, locate a globally accessible archive of the library's sources. Zip, gzip, and bzip are all supported. Strongly prefer official sources or mirrors over unofficial mirrors.
Looking at zlib's website, the URL http://zlib.net/zlib128.zip looks appropriate.
Second, determine a suitable package name. This should be ASCII, lowercase, and recognizable to someone who knows the library's "human name". If the library is already packaged in another package manager, prefer that name.
Since zlib is already packaged as zlib, we will use the name zlib2 for this example.
Finally, if the server's name for the archive is not very descriptive (such as downloading a zipped commit or branch from GitHub), choose a nice archive name of the form <packagename>-<version>.zip.
zlib128.zip is a fine name, so no change needed.
All this information can then be passed into the create command, which will download the sources and bootstrap the packaging process inside ports\<packagename>.
PS D:\src\vcpkg> .\vcpkg create zlib2 http://zlib.net/zlib128.zip zlib128.zip
-- Generated portfile: D:/src/vcpkg/ports/zlib2/portfile.cmake
In addition to the generated ports\<package>\portfile.cmake, We also need a ports\<package>\CONTROL file. This file is a simply formatted set of fields describing the package's metadata.
For zlib2, we'll create the file ports\zlib2\CONTROL with the following contents:
Source: zlib2
Version: 1.2.8
Description: A Massively Spiffy Yet Delicately Unobtrusive Compression Library
The generated portfile.cmake will need some editing to correctly package most libraries in the wild, however we can start by trying out the build.

At this point, it is a matter of reading the error messages and log files while steadily improving the quality of the portfile. Zlib required providing a discrete copy of the LICENSE to copy into the package, suppressing the build and installation of executables and headers, and removing the static libraries after they were installed.
In the ports\ directory are many libraries that can be used as examples, including many that are not based on CMake.

- MSBuild-based
- mpg123
- glew
