Crypto++ CMake

Build Status Build status

This repository contains CMake files for Wei Dai's Crypto++ ( It supplies CMakeLists.txt and cryptopp-config.cmake for Crypto++ for those who want to use CMake. CMake is officialy unsupported, so use it at your own risk.

The purpose of Crypto++ CMake is two-fold:

  1. better support Linux distributions, like Gentoo
  2. provide users with centrally maintained CMake project files

The initial cryptopp-config.cmake and CMakeLists.txt were taken from the library sources when CMake support was dropped. Also see CMake on the Crypto++ wiki for some history and how to use CMake with Crypto++.


The CMake project files are documented on the Crypto++ wiki | CMake. If there is an error or ommission in the wiki article, then please fix it or open a bug report.


The CMake files are officialy unsupported, so use them at your own risk. With that said, the CMake source files are tested with Crypto++ on Linux and OS X using Travis CI.

In June 2018 the library added to help test the CMake gear. The script is located in Crypto++'s TestScripts directory. The script downloads the CMake project files, builds the library and then runs the self tests.

If you want to use to drive things then perform the following steps.

cd cryptopp
cp TestScripts/ .


The general workflow is clone Wei Dai's crypto++, add CMake as a submodule, and then copy the files of interest into the Crypto++ directory:

git clone
cd cryptopp

wget -O CMakeLists.txt
wget -O cryptopp-config.cmake

Despite our efforts we have not been able to add the submodule to Crypto++ for seamless integration. If anyone knows how to add the submodule directly to the Crypto++ directory, then please provide the instructions.

ZIP Files

If you are working from a Crypto++ release zip file, then you should download the same cryptopp-cmake release zip file. Both Crypto++ and this project use the same release tags, such as CRYPTOPP_8_0_0.

If you mix and match Master with a release zip file then things may not work as expected. You may find the build project files reference a source file that is not present in the Crypto++ release.


The CMake submodule integrates with the Crypto++ library. The library's GNUmakefile and GNUmakefile-cross were modified to clean the artifacts produced by CMake. To clean the directory after running CMake perform a git checkout GNUmakefile followed by a make -f GNUmakefile distclean.


We would like all distro maintainers to be collaborators on this repo. If you are a distro maintainer then please contact us so we can send you an invite.

If you are a collaborator then make changes as you see fit. You don't need to ask for permission to make a change. Noloader is not an CMake expert so there are probably lots of opportunities for improvement.

Keep in mind other distros may be using the files, so try not to break things for the other guy. We have to be mindful of lesser-used platforms and compilers, like AIX, Solaris, IBM xlC and Oracle's SunCC.


Everything in this repo is release under Public Domain code. If the license or terms is unpalatable for you, then don't feel obligated to use it or commit.
