That is the case for re2::StringPiece and absl::string_view
and happens to be the case for std::string_view in libstdc++
and libc++, but std::string_view in MSVC has iterators that
aren't just pointers.

Fixes #214.

There are two changes in this patch but they are related because they
both improve install target generated by CMake.

1) GNUInstallDirs is now used to determine name of the folders where
libraries and headers are installed. On RedHat based Linux
distributions, usual folder for x86-64 libraries is lib64 and not just
simply lib. GNUInstallDirs takes care of deciding which name to use.

2) Pkgconfig file was not installed when CMake was used. Adding pc file
to the installation process of CMake install target allows package
maintainers to easily provide packages which work both with pkgconfig
and CMake.

Fixes #215.

If CMake doesn't support building libre2.a and libre2.so together and
installing them together, then it isn't suitable for use in packaging
and so installing re2.pc isn't needed.

Fixes #215.
