777928035dbcbf39f361eb7d10dc3696822f692f by Jon Cohen <cohenjon@google.com>:

Add install rules for Abseil CMake.

These are attempted to be limited to in-project installation.  This serves two purposes -- first it's morally the same as using Abseil in-source, except you don't have to rebuild us every time.  Second, the presence of an install rule makes life massively simpler for package manager maintainers.

Currently this doesn't install absl tests or testonly libraries.  This can be added in a follow-up patch.

Fixes #38, Fixes #80, Closes #182

// File: substitute.h
// -----------------------------------------------------------------------------
//
// This package contains functions for efficiently performing string
// substitutions using a format string with positional notation:
// `Substitute()` and `SubstituteAndAppend()`.
//
// Unlike printf-style format specifiers, `Substitute()` functions do not need
// to specify the type of the substitution arguments. Supported arguments
// following the format string, such as strings, string_views, ints,
// floats, and bools, are automatically converted to strings during the
// substitution process. (See below for a full list of supported types.)
//
// `Substitute()` does not allow you to specify *how* to format a value, beyond
// the default conversion to string. For example, you cannot format an integer
// in hex.
//
// The format string uses positional identifiers indicated by a dollar sign ($)
// and single digit positional ids to indicate which substitution arguments to
// use at that location within the format string.
//
// Example 1:
// std::string s = Substitute("$1 purchased $0 $2. Thanks $1!",
// 5, "Bob", "Apples");
// EXPECT_EQ("Bob purchased 5 Apples. Thanks Bob!", s);
//
// Example 2:
// std::string s = "Hi. ";
// SubstituteAndAppend(&s, "My name is $0 and I am $1 years old.", "Bob", 5);
// EXPECT_EQ("Hi. My name is Bob and I am 5 years old.", s);
//
// Supported types:
// * absl::string_view, std::string, const char* (null is equivalent to "")
// * int32_t, int64_t, uint32_t, uint64
// * float, double
// * bool (Printed as "true" or "false")
// * pointer types other than char* (Printed as "0x<lower case hex string>",
// except that null is printed as "NULL")
//
// If an invalid format string is provided, Substitute returns an empty string
// and SubstituteAndAppend does not change the provided output string.
// A format string is invalid if it:
// * ends in an unescaped $ character,
// e.g. "Hello $", or
// * calls for a position argument which is not provided,
// e.g. Substitute("Hello $2", "world"), or
// * specifies a non-digit, non-$ character after an unescaped $ character,
// e.g. "Hello $f".
// In debug mode, i.e. #ifndef NDEBUG, such errors terminate the program.
