RPly is a library that lets applications read and write PLY files. The PLY file format is widely used to store geometric information, such as 3D models, but is general enough to be useful for other purposes.

libLAS is a C/C++ library for reading and writing the very common LAS LiDAR format.

FLANN is a library for performing fast approximate nearest neighbor searches in high dimensional spaces.

Non-Metric Space Library (NMSLIB): An efficient similarity search library and a toolkit for evaluation of k-NN methods for generic non-metric spaces.

Zstandard, or zstd as short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library.
