cmake: Remove optional definitions from `bitcoin-build-config.h` #35072

pull hebasto wants to merge 5 commits into bitcoin:master from hebasto:260414-sans-gui-config changing 25 files +12 −61

hebasto commented at 5:33 PM on April 14, 2026: member
On the master branch, modifying optional settings to reconfigure the build system triggers unnecessary rebuilds.

For example, consider the following workflow:
```
cmake -B build -DBUILD_TESTS=OFF
cmake --build build
cmake -B build -DBUILD_TESTS=OFF -DBUILD_GUI=ON
cmake --build build
```
The final command should only build bitcoin-qt and bitcoin-gui, but instead, it unnecessarily rebuilds other targets as well.

This occurs because optional definitions like USE_DBUS and USE_QRCODE are included in bitcoin-build-config.h. Modifying these settings alters the header, triggering a recompilation of every target that consumes it.

This PR resolves the issue. While beneficial on its own, it also serves as a necessary prerequisite for effectively addressing #29914.

Tested ACK 9f65a7a4942c1addf3efed47a64a54b0889215bf

Tested that only Qt-related targets are rebuilt when BUILD_GUI=ON is enabled. Non-GUI targets (bitcoind, bitcoin-node, bitcoin, bitcoin_clientversion, bitcoin_util, etc.) remain untouched.

Tested on Ubuntu 24.04.4 LTS

cmake -B build -DBUILD_TESTS=OFF
cmake --build build
cmake -B build -DBUILD_TESTS=OFF -DBUILD_GUI=ON
cmake --build build

but it is also a necessary prerequisite for effectively addressing #29914.

It would be good to see the changes that require this. The same logic applies to other optional dependencies, so it'd be good to be clear about what should live in build-config.h, or shouldn't, and why this needs to be moved out.

cmake: Move `USE_DBUS` to `bitcoinqt` target

This removes the `USE_DBUS` definition from `bitcoin-build-config.h`,
reducing the dependency of non-GUI code on GUI-specific definitions.

cmake: Move `USE_QRCODE` to `bitcoinqt` target

This removes the `USE_QRCODE` definition from `bitcoin-build-config.h`,
reducing the dependency of non-GUI code on GUI-specific definitions.

Additionally, `QRencode::QRencode` is now linked only when wallet is
enabled, because the `qrencode.h` header is used exclusively in
wallet-specific code.

cmake: Move `ENABLE_WALLET` to `bitcoinqt` and `test_bitcoin-qt` targets

This removes the `ENABLE_WALLET` definition from
`bitcoin-build-config.h`, reducing the dependency of core code on the
optional definitions.

cmake: Move `ENABLE_TRACING` to `USDT::headers` target

This removes the `ENABLE_TRACING` definition from
`bitcoin-build-config.h`, reducing the dependency of core code on the
optional definitions.

Additionally, the `FindUSDT` module is refactored to use
`target_include_directories` instead of `set_target_properties`.

but it is also a necessary prerequisite for effectively addressing #29914.

It would be good to see the changes that require this. The same logic applies to other optional dependencies, so it'd be good to be clear about what should live in build-config.h, or shouldn't, and why this needs to be moved out.

Reworked. The PR description has been updated.

PR #33828 has gen-manpages.py read build/src/bitcoin-build-config.h for a few macros (HAVE_SYSTEM, ENABLE_WALLET, WITH_ZMQ). As optional defines move out of that header: it would be nice to have a single source of truth for “what was enabled” for this kind of tooling, though combining sources (header where it still exists, CMakeCache.txt or similar otherwise) may be fine. That ties into the earlier thread here about what belongs in build-config.h vs elsewhere—any guidance on what you’d prefer for scripts like this?
