   Somewhat similar to #31745. If you build --target deploy and then try and cmake --install, it will fail:

    0cmake -B build --toolchain /root/ci_scratch/depends/x86_64-w64-mingw32/toolchain.cmake -DCMAKE_INSTALL_PREFIX=/root/testing
    1cmake --build build --target deploy

   Maybe this isn’t a supported workflow? Not completely sure, but I can imagine someone running into this after using the Windows build docs. I did testing #32002.

   I think this behaviour is expected since test_bitcoin-qt.exe is not part of the Windows installer and is not required for the deploy target.

   Additionally, in WINDOWS BUILD NOTES, cmake --install build follows cmake --build build, and this sequence always works.

   Note that this isn’t Windows specific. The same happens for macOS build.

   From the CMake docs:

   By default, the install target depends on the all target. This has the effect, that when make install is invoked or INSTALL is built, first the all target is built, then the installation starts.

   On the other hand, the cmake --install <dir> command:

   … may be used after building a project to run installation without using the generated build system or the native build tool.

   Therefore, I’d say that the workflow described in the OP is unsupported. However, the user could instead use the following one:

   0cmake -B build --toolchain /root/ci_scratch/depends/x86_64-w64-mingw32/toolchain.cmake -DCMAKE_INSTALL_PREFIX=/root/testing
   1cmake --build build --target deploy
   2cmake --build build --target install
