Since commit 8d83487e60 (CONTRIBUTORS: Factor contributors list out of
license file, 2025-03-02) the copyright line has reStructuredText
markup. Filter it out of the copyright line printed by `bootstrap`.
This dependency is not expressed in upstream libuv. It was added to
CMake by commit 6a497bb0a3 (libuv: Link with kvm on FreeBSD, 2016-09-08,
v3.7.0-rc1~143^2~1). It is needed only on NetBSD.
Fixes: #26722
Add a helper class to read CPS files. Use this to teach find_package how
to consider and accept .cps files in its search. (Note that no version
testing is performed at this time.) Add a simple test that we can find a
package from a .cps file and correctly extract the version information.
Note that this doesn't actually import anything from CPS yet.
Create a `cm::PathResolver` helper to compute normalized paths.
Provide a common implementation with compile-time dispatch to
select details w.r.t. symbolic links, existence, and matching
the on-disk case of existing paths. Later we can use this to
implement:
* `ToNormalizedPathOnDisk`: Normalizes paths while resolving symlinks
only when followed by `..` components. Does not require paths to
exist, but reads on-disk case of paths that do exist (on Windows).
* `GetRealPath`: Normalizes paths while resolving all symlinks.
Requires paths to exist, and reads their on-disk case (on Windows).
* `CollapseFullPath`: Normalizes paths in memory without disk access.
Assumes components followed by `..` components are not symlinks.
Abstract filesystem access through runtime dispatch so that we can test
Windows symbolic link and network path behavior without relying on real
environments. The overhead of runtime dispatch should be insignificant
during real filesystem access.

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.
35eb28bc76 bootstrap: Restore support for system jsoncpp and uv without pkg-config

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.
