Describe Bug

There is no way to set build type (--debug or --release) in qt.deploy.flags passed to windeployqt. There is a logic inside xmake where it internally set build type passed to windeployqt determined by general build type.

But there is need to pass custom debug or release option to windeployqt when the general project build type is set to debug, but Qt is build as a release (most of the cases it's release). In this case, passing --debug to windeployqt led to the following error:

PS D:\dev\cpp\qt6-example> xmake install -o build/install -v

error: install failed, execv(C:\Qt\mingw\bin\windeployqt.exe --force --verbose=1 --debug build\install\bin\qt6-example.exe) failed(1)

When I set, for example: set_values("qt.deploy.flags", {"--release"}) it leads to duplicated build type options (... --debug --release ...) passed to windeployqt:

C:\Qt\mingw\bin\windeployqt.exe --force --verbose=1 --debug --release build\install\bin\qt6-example.exe

Expected Behavior

Flags passed via set_values("qt.deploy.flags", {"--release"}) should have priority over default flags (--debug or --release) added internally by xmake and not led to duplicated options.

Project Configuration

add_rules("mode.debug", "mode.release")
set_config("mode", "debug") -- Set default mode to debug
add_rules("plugin.compile_commands.autoupdate", {outputdir = "build"}) -- Generate compile_commands.json
set_targetdir("$(buildir)/bin")
set_languages("c++20")

if is_plat("mingw") then
    add_ldflags("-static")
end

set_values("qt.deploy.flags", {"--release"})

target("qt6-example")
    add_rules("qt.widgetapp")
    add_frameworks("QtNetwork")
    add_files(
        "main.cpp",
        "mainwindow.cpp",
        "mainwindow.h",
        "mainwindow.ui",
        "resources.qrc"
    )
