Vcpkg
C++ Library Manager for Windows, Linux, and MacOS
Vcpkg helps you manage C and C++ libraries on Windows, Linux and MacOS. This tool and ecosystem are constantly evolving, and we always appreciate contributions! After you've gotten vcpkg installed and working, you may wish to add tab completion to your shell. With CMake, you will still need to find_package and the like to use the libraries. Check out the CMake section for more information, including on using CMake with an IDE. In classic mode, vcpkg produces an "installed" tree, whose contents are changed by explicit calls to vcpkg install or vcpkg remove. The installed tree is intended for consumption by any number of projects: for example, installing a bunch of libraries and then using those libraries from Visual Studio, without additional configuration. Because the installed tree is not associated with an individual project, it's similar to tools like brew or apt, except that the installed tree is vcpkg-installation-local, rather than global to a system or user. -

IRremote Arduino Library
Infrared remote library for Arduino, send and receive infrared signals
This library enables you to send and receive using infra-red signals on an Arduino. You can use any pin for sending now like you are used to receiving. Simultaneous sending and receiving. See the SendAndReceive example. No more need to use 32-bit hex values in your code. Instead, a (8 bit) command value is provided for decoding (as well as a 16-bit address and a protocol number). Protocol values comply to protocol standards, i.e. NEC, Panasonic, Sony, Samsung, and JVC decode and send LSB first. Supports more protocols, since adding a protocol is quite easy now. Better documentation and more examples. Compatible with tone() library, see ReceiveDemo. Supports more platforms, since the new structure allows to easily add a new platform. Feedback LED also for sending. Ability to generate a non-PWM signal to just simulate an active low receiver signal for direct connection to existent receiving devices without using IR. -

LevelDB
A fast key-value storage library
LevelDB is a library of persistent key values. Written at Google, it contains keys and values that are arbitrary byte arrays, ordered within the key value store according to a user-specified comparator function. LevelDB is not an SQL database and does not support SQL queries or indexes. It simply provides an ordered mapping from string keys to string values. Data is stored already sorted by key, though callers can override the sort order through a custom comparison function. It supports forward and backward iteration as well as transient snapshots, and automatically compresses data via the Snappy compression library. -

cpp-httplib
A C++ header-only HTTP/HTTPS server and client library
A C++11 single-file header-only cross-platform HTTP/HTTPS library. It's extremely easy to setup. Just include the httplib.h file in your code! This is a multi-threaded 'blocking' HTTP library. If you are looking for a 'non-blocking' library, this is not the one that you want. SSL support is available with CPPHTTPLIB_OPENSSL_SUPPORT. libssl and libcrypto should be linked. When using SSL, it seems impossible to avoid SIGPIPE in all cases, since on some operating systems, SIGPIPE can only be suppressed on a per-message basis, but there is no way to make the OpenSSL library do so for its internal communications. If your program needs to avoid being terminated on SIGPIPE, the only fully general way might be to set up a signal handler for SIGPIPE to handle or ignore it yourself. cpp-httplib officially supports only the latest Visual Studio. It might work with former versions of Visual Studio, but I can no longer verify it. -

rtabmap
RTAB-Map library and standalone application
RTAB-Map (Real-Time Appearance-Based Mapping) is a RGB-D, Stereo and Lidar Graph-Based SLAM approach based on an incremental appearance-based loop closure detector. The loop closure detector uses a bag-of-words approach to determine how likely a new image comes from a previous location or a new location. When a loop closure hypothesis is accepted, a new constraint is added to the map’s graph, then a graph optimizer minimizes the errors in the map. A memory management approach is used to limit the number of locations used for loop closure detection and graph optimization so that real-time constraints on large-scale environments are always respected. RTAB-Map can be used alone with a handheld Kinect, a stereo camera or a 3D lidar for 6DoF mapping, or on a robot equipped with a laser rangefinder for 3DoF mapping. -
