9e5089dbb0 build, msvc: Enable `libqrencode` vcpkg package (Hennadii Stepanov)
30089b0cb6 cmake: Add `FindQRencode` module (Hennadii Stepanov)
Pull request description:
This PR introduces the `FindQRencode` CMake module, following the official CMake [guidelines](https://cmake.org/cmake/help/latest/manual/cmake-developer.7.html#find-modules) for managing [upstream libraries](https://github.com/fukuchi/libqrencode) that lack a config file package. This module enhances flexibility in locating the `libqrencode` library by making the use of `pkg-config` optional.
With this update, `libqrencode` can be detected on systems where either `pkg-config` or the `libqrencode.pc` file is unavailable, such as Windows environments using the vcpkg package manager. However, if `libqrencode.pc` is available, it remains beneficial as the only direct source of the library's version information.
Additionally, the `libqrencode` vcpkg package is enabled for MSVC builds.
Here is a diff for configuration output on Ubuntu 24.10:

fafbf8acf4 Make G_FUZZING constexpr, require -DBUILD_FOR_FUZZING=ON to execute a fuzz target (MarcoFalke)
fae3cf0ffa ci: Temporarily disable macOS/Windows fuzz step (MarcoFalke)
Pull request description:
`g_fuzzing` is used inside `Assume` at runtime, causing significant overhead in hot paths. See https://github.com/bitcoin/bitcoin/issues/31178
One could simply remove the `g_fuzzing` check from the `Assume`, but this would make fuzzing a bit less useful. Also, it would be unclear if `g_fuzzing` adds a runtime overhead in other code paths today or in the future.
Fix all issues by making `G_FUZZING` equal to the build option `BUILD_FOR_FUZZING`, and for consistency in fuzzing, require it to be set when executing any fuzz target.
Fixes https://github.com/bitcoin/bitcoin/issues/31178
Temporarily this drops fuzzing from two CI tasks, but they can be re-added in a follow-up with something like https://github.com/bitcoin/bitcoin/pull/31073

I still ACK https://github.com/bitcoin/bitcoin/pull/31191/commits/fafbf8acf419d5e2ca307e5804099361ca7471af for fixing the regression measured in #31178.
ryanofsky:
Code review ACK fafbf8acf4 but approach -0, because this approach means libraries built for fuzz testing do not function correctly if used in a release, and libraries built for releases are mostly useless for fuzz testing. So I would like to at least consider other solutions to this problem even if we go with this one.

2957ca9611 build: have "make test" depend on "make all" (Cory Fields)
Pull request description:
See [Upstream docs](https://cmake.org/cmake/help/latest/variable/CMAKE_SKIP_TEST_ALL_DEPENDENCY.html) for specifics.
Unfortunately, this **seems to have no effect when directly executing `ctest`** :(
This brings the test -> hack -> test cycle more inline with how it worked with autotools.
With `CMAKE_SKIP_TEST_ALL_DEPENDENCY` set to FALSE, `make test` will trigger a rebuild, ensuring that test binaries are current before running them.
To test:
```
cmake -S . -B build
make -C build -j24
touch src/primitives/transaction.cpp
make -C build test ARGS=-j24
```
Without this commit, the above will not rebuild before running tests.

6b8a74463b cmake: Add `FindZeroMQ` module (Hennadii Stepanov)
Pull request description:
This PR introduces the `FindZeroMQ` module, which first attempts to find the `libzmq` library using CMake's `find_package()` and falls back to `pkg_check_modules()` if unsuccessful.
Addresses https://github.com/bitcoin/bitcoin/issues/30876 for the ZeroMQ package.

The use of `PACKAGE_NAME` for the project's variable name is
problematic, as this name is commonly used in CMake's interface
variables. If third-party CMake code handles with scopes improperly,
our `PACKAGE_NAME` variable could end up with an unexpected value.
This change avoids such conflicts by renaming all `PACKAGE_*` variables
to `CLIENT_*`.
9f243cd7fa Introduce `g_fuzzing` global for fuzzing checks (dergoegge)
Pull request description:
This PR introduces a global `g_fuzzing` that indicates if we are fuzzing.
If `g_fuzzing` is `true` then:
* Assume checks are enabled
* Special fuzzing paths are taken (e.g. pow check is reduced to one bit)

fa1b139d17 Bump python minimum supported version to 3.10 (MarcoFalke)
Pull request description:
All supported operating systems ship with python 3.10 (or later), so bumping the minimum should not cause any issues. A bump will allow new code to use new python features.
For reference:
* https://packages.debian.org/bookworm/python3
* https://packages.ubuntu.com/jammy/python3
* FreeBSD 13/14 ships with 3.11
* CentOS-like 8/9 ships with 3.11/3.12 (via `appstream`)
* OpenSuse Tumbleweed ships with all python versions, e.g. https://software.opensuse.org/package/python312-base
This is for Bitcoin Core 29.0 in 2025 (next year), not the soon upcoming 28.0 this fall.

The removed commands were left over from the transition from
autodetection to explicit options. These commands prevented the
`-DENABLE_WALLET=OFF` option from being work properly when building with
depends.
30803a35d5 cmake: decouple FORTIFY_SOURCE check from Debug build type (fanquake)
Pull request description:
`FORTIFY_SOURCE` should be used if `ENABLE_HARDENING=ON` and optimisations are being used. This should not be coupled to any particular build type, because even if the build type is `Debug`, optimisations might still be in use.
Fixes: #30800.
Also somewhat of a followup to https://github.com/bitcoin/bitcoin/pull/30778#discussion_r1742257436.
