36b6f36ac4724cb2c9ed0e25314c3bbf55e4ebb8 build: require sqlite when building the wallet (Sjors Provoost)
Pull request description:
Require that sqlite is available in order to compile the wallet. Removes instances of `USE_SQLITE` since it is no longer possible to not have sqlite available.
The `NO_SQLITE` option is dropped from depends.
This is another step towards dropping the legacy wallet, extracted from #31250.

026bb226e96919603af829d0b677779a234a0f6e cmake: Set top-level target output locations (Hennadii Stepanov)
Pull request description:
This PR sets the target output locations to the `bin` and `lib` subdirectories within the build tree, creating a directory structure that mirrors that of the installed targets.
This approach is widely adopted by the large projects, such as [LLVM](e146c1867e/lldb/cmake/modules/LLDBStandalone.cmake (L128-L130)):
```cmake
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
```
The `libsecp256k1` project has also recently [adopted](https://github.com/bitcoin-core/secp256k1/pull/1553) this approach.
With this PR, all binaries are conveniently located. For example, run:
```
$ ./build/bin/fuzz
```
instead of:
```
$ ./build/src/test/fuzz/fuzz
```
On Windows, all required DLLs are now located in the same directory as the executables, allowing to run `bitcoin-chainstate.exe` (which loads `bitcoinkernel.dll`) without the need to copy DLLs or modify the `PATH` variable.
The idea was briefly discussed among the build team during the recent CoreDev meeting.
---
**Warning**: This PR changes build locations of newly built executables like `bitcoind` and `test_bitcoin` from `src/` to `bin/` without deleting previously built executables. A clean build is recommended to avoid accidentally running old binaries.

This PR ensures that `CMAKE_TRY_COMPILE_TARGET_TYPE` is modified only within local scopes.
Additionally, the `FUZZ_LIBS` variable has been introduced to handle additional libraries required for linking, rather than link options, in certain build environment, such as OSS-Fuzz.

CMake distinguishes recommended methods for handling (1) linker options
and (2) libraries used during linking. Therefore, it is both reasonable
and consistent to introduce a dedicated variable for the latter,
particularly when a build environment, such as OSS-Fuzz, requires
linking against additional libraries.

dead9086543671b07e6ce041821e4d2a6627075b cmake: Improve compatibility with Python version managers (Hennadii Stepanov)
Pull request description:
This PR resolves the issue [highlighted](https://github.com/bitcoin/bitcoin/pull/31411#issuecomment-2516745547) in https://github.com/bitcoin/bitcoin/pull/31411:
> Here's another case where CMake just picks some other Python...
The fix leverages two [hints](https://cmake.org/cmake/help/latest/module/FindPython3.html#hints) for the CMake `FindPython3` module:
1. `Python3_FIND_FRAMEWORK` is set to `LAST`. This ensures that Unix-style package components are preferred over frameworks on macOS. As a side effect, the `FindPython3` module reports a shim or symlink (e.g., from `pyenv`) rather than the underlying framework's binary. The module's output aligns with the result of the `which` command.
2. `Python3_FIND_UNVERSIONED_NAMES` is set to `FIRST`. This supports scenarios where tools like `pyenv`—which use shims—have multiple Python versions installed.
Here are examples of output on my macOS 15.1.1 (Intel) with installed Homebrew's [Python 3.13.0](https://formulae.brew.sh/formula/python@3.13):
- without any Python version manager:
```
% which -a python3
/usr/local/bin/python3
/usr/bin/python3
% cmake -B build
<snip>
-- Found Python3: /usr/local/bin/python3 (found suitable version "3.13.0", minimum required is "3.10") found components: Interpreter
<snip>
```
- using `pyenv`:
```
% pyenv versions
system
* 3.10.14 (set by /Users/hebasto/dev/bitcoin/.python-version)
3.12.8
3.13.1
% which -a python3
/Users/hebasto/.pyenv/shims/python3
/usr/local/bin/python3
/usr/bin/python3
% cmake -B build
<snip>
-- Found Python3: /Users/hebasto/.pyenv/shims/python3 (found suitable version "3.10.14", minimum required is "3.10") found components: Interpreter
<snip>
```
Both variables, `Python3_FIND_FRAMEWORK` and `Python3_FIND_UNVERSIONED_NAMES`, can still be overridden by the user via the command line if needed.

Generally they allow for jobservers (either `make -jX` or `ninja`) to be better utilized. This can be verified using `top` while building and looking at the number of compiles running at any given time before/after these changes. Before, it's easy to observe periods of stalling when only one or two compiles are happening. After these changes, the compiler process count should mostly match the number of jobs given (`-jX`) until it falls off at the end.

The first commit sets [DEPENDS_EXPLICIT_ONLY](https://cmake.org/cmake/help/latest/command/add_custom_command.html#command:add_custom_command) for commands which generate our test header files. Without this option, `test_bitcoin`'s generated headers won't be built until all of its other dependencies have been built. This introduces a significant stall in the build, though currently only Ninja benefits from this being set, and only CMake >= 3.27 understands it.
Example from a generated `build.ninja`:
Before:
> \# Custom command for src/test/data/base58_encode_decode.json.h

The second commit is more significant. It sets [CMAKE_OPTIMIZE_DEPENDENCIES](https://cmake.org/cmake/help/latest/prop_tgt/OPTIMIZE_DEPENDENCIES.html) globally, which allows the objects of static libs to be built in parallel when one lib depends on the other. This can be set as a per-lib property, ~but I don't see any need for that as we don't currently have any edge-cases where this wouldn't be ok. If those should arise, we could always disable on a per-lib basis~.
Edit: turns out this triggers an [upstream bug](https://gitlab.kitware.com/cmake/cmake/-/issues/24058), which I guess can be considered an edge-case until fixed in CMake. I've added 2 per-lib opt-outs as a result.
Example:
Before:
> \# Link the static library src/libbitcoin_cli.a

This ensures that most compiler tests are not run with the wrong build type's flags. The initial c++ checks are an exception to that because many internal CMake variables are unset until a language is selected, so it's problematic to change our build type before that.
The difference can be seen in `build/CMakeFiles/CMakeConfigureLog.yaml`. Before, `Debug` was used for many of the earlly checks. After this PR, it's only the first 2 checks.

Pull request description:
This implements a safegcd-based modular inverse for MuHash3072. It is a fairly straightforward translation of [the libsecp256k1 implementation](https://github.com/bitcoin-core/secp256k1/pull/831), with the following changes:
* Generic for 32-bit and 64-bit
* Specialized for the specific MuHash3072 modulus (2^3072 - 1103717).
* A bit more C++ish
* Far fewer sanity checks
A benchmark is also included for MuHash3072::Finalize. The new implementation is around 100x faster on x86_64 for me (from 5.8 ms to 57 μs); for 32-bit code the factor is likely even larger.

Windows cross builds using `-O0` currently fail to compile, as some
objects have too many sections. As a convenience, add `-mbig-obj` to
our compile flags when using the `Debug` build type, so that if someone
tries to build this way, it will work.
This would also be needed if we switched the depends flags to -O0.
`-mbig-obj`
> On PE/COFF target this option forces the use of big object
> file format, which allows more than 32768 sections.

on GCC or `-fcoverage-prefix-map` on Clang, which can lead to issues
with coverage builds.
This change applies only the options necessary for build reproducibility
and accurate source location messages.
While we will only outwardly support Windows 10+, due to an issue in
mingw-w64, we can't set the *-subsystem-version values higher than to
target Windows 8, so do that as a best effort.

30089b0cb61c1c40d6338877ffd5d72b31024271 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.

fafbf8acf419d5e2ca307e5804099361ca7471af Make G_FUZZING constexpr, require -DBUILD_FOR_FUZZING=ON to execute a fuzz target (MarcoFalke)
fae3cf0ffa619f8fe7e4ace1889fe7abbb53a532 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

ryanofsky:
Code review ACK fafbf8acf419d5e2ca307e5804099361ca7471af 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.

2957ca9611916efb570d157b9c7a0b188161660d 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.

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_*`.
9f243cd7fa6654e3b71ba6bff82cceed547c5d53 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)
