In order to support generation of Common Package Specifications, the
mechanisms CMake uses to export package information need to be made more
abstract. The prior commits began this refactoring; this continues by
(actually) restructuring the classes used to generate the actual export files.
To minimize churn, this introduces virtual base classes and
diamond inheritance in order to separate logic which is format-agnostic
but depends on the export mode (build-tree versus install-tree) from
logic which is format-specific but mode-agnostic.
This could probably be refactored further to use helper classes instead,
and a future commit may do that, however an initial attempt to do that
was proving even more invasive, such that this approach was deemed more
manageable.
While we're at it, add 'const' in more places where possible.
In commit da5de7f9f3 (bootstrap: Allow --boostrap-system-* libraries
custom prefixes, 2024-03-03, v3.30.0-rc1~456^2) the non-pkg-config code
path for uv/jsoncpp/rhash all set `use_librhash_ldflags` instead of
their own variable.
In order to support generation of Common Package Specifications, the
mechanisms CMake uses to export package information need to be made more
abstract. As a first step toward this, refactor cmInstallExportGenerator
so that logic specific to config.cmake and Android .mk lives in separate
subclasses.
While we're at it, clean up the code style a bit and try to use moves a
bit more consistently.
This is step 1 of 2. The next step will refactor the individual file
generators along similar lines, which will also involve creating
additional classes for format-agnostic logic that is shared between
build-tree and install-tree variants.
Our vendored curl only enables the Secure Transport backend by default
(`CURL_SSL_BACKEND=secure-transport`), but it is limited to TLS 1.2.
The macOS SDK provides the curl development components, and the
corresponding `libcurl.4.dylib` runtime library comes with macOS.
On macOS 12 and above, the default `CURL_SSL_BACKEND=openssl`
backend seems to be capable of selecting TLS 1.3 at runtime for
https connections.
Unfortunately the macOS version of curl, even on macOS 14.4, does
not accept `CURL_SSLVERSION_TLSv1_3` at runtime to enforce TLS 1.3.
However, while our vendored curl accepts the option and passes it
to Secure Transport, macOS does not actually enforce it anyway.

If pkg-config is available, we can query it for the correct -l/-L flags.
This fixes the --boostrap-libuv build for me with libuv installed into
$HOME and PKG_CONFIG_PATH set appropriately

When importing a C++ module, there may be requirements imposed by the
importer so that the compiler can reliably read the BMI. For example,
the standard used in the importer may need to also apply to the imported
BMI.
Right now, there are no tracked requirements. As we learn more, this
class can start tracking more information.

Rather than treating the user-provided CXX as a space-separated series of
compilers, treat it as a single command-line fragment which possibly
contains flags.

Since commit 5c58a7e4d2 (ppc64: Work around TOC overflow with platform
specific linker flags, 2019-02-27, v3.15.0-rc1~460^2) we use a bigtoc
flag on this platform when building CMake with CMake. Add it to the
bootstrap script too.
