CMake: Install TESTONLY libraries and their dependencies (#1442) This patch cherry-picks 807763a7f57dcf0ba4af7c3b218013e8f525e811 #1407 --------- Co-authored-by: Derek Mauro <email@example.com>
The repository contains the Abseil C++ library code. Abseil is an open-source collection of C++ code (compliant to C++14) designed to augment the C++ standard library.
Abseil is an open-source collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's own C++ code base, has been extensively tested and used in production, and is the same code we depend on in our daily coding lives.
In some cases, Abseil provides pieces missing from the C++ standard; in others, Abseil provides alternatives to the standard for special needs we've found through usage in the Google code base. We denote those cases clearly within the library code we provide you.
Abseil is not meant to be a competitor to the standard library; we've just found that many of these utilities serve a purpose within our code base, and we now want to provide those resources to the C++ community as a whole.
If you want to just get started, make sure you at least run through the Abseil Quickstart. The Quickstart contains information about setting up your development environment, downloading the Abseil code, running tests, and getting a simple binary working.
Bazel and CMake are the official build systems for Abseil. See the quickstart for more information on building Abseil using the Bazel build system. If you require CMake support, please check the CMake build instructions and CMake Quickstart.
Abseil follows Google's Foundational C++ Support Policy. See this table for a list of currently supported versions compilers, platforms, and build tools.
Abseil contains the following C++ library components:
baselibrary contains initialization code and other code which all other Abseil code depends on. Code within
basemay not depend on any other code (other than the C++ standard library).
algorithmlibrary contains additions to the C++
<algorithm>library and container-based versions of such algorithms.
cleanuplibrary contains the control-flow-construct-like type
absl::Cleanupwhich is used for executing a callback on scope exit.
containerlibrary contains additional STL-style containers, including Abseil's unordered “Swiss table” containers.
crclibrary contains code for computing error-detecting cyclic redundancy checks on data.
debugginglibrary contains code useful for enabling leak checks, and stacktrace and symbolization utilities.
flagslibrary contains code for handling command line flags for libraries and binaries built with Abseil.
hashlibrary contains the hashing framework and default hash functor implementations for hashable types in Abseil.
iteratorlibrary contains utilities for augmenting ranges in range-based for loops.
CHECKmacros and facilities for writing logged messages out to disk,
stderr, or user-extensible destinations.
memorylibrary contains memory management facilities that augment C++'s
metalibrary contains compatible versions of type checks available within C++14 and C++17 versions of the C++
numericlibrary contains 128-bit integer types as well as implementations of C++20's bitwise math functions.
profilinglibrary contains utility code for profiling C++ entities. It is currently a private dependency of other Abseil libraries.
randomlibrary contains functions for generating psuedorandom values.
statuslibrary contains abstractions for error handling, specifically
stringslibrary contains a variety of strings routines and utilities, including a C++14-compatible version of the C++17
synchronizationlibrary contains concurrency primitives (Abseil's
absl::Mutexclass, an alternative to
std::mutex) and a variety of synchronization abstractions.
timelibrary contains abstractions for computing with absolute points in time, durations of time, and formatting and parsing time within time zones.
typeslibrary contains non-container utility types, like a C++14-compatible version of the C++17
utilitylibrary contains utility and helper code.
Abseil recommends users “live-at-head” (update to the latest commit from the master branch as often as possible). However, we realize this philosophy doesn't work for every project, so we also provide Long Term Support Releases to which we backport fixes for severe bugs. See our release management document for more details.
