Question

我注意到qmake和CMake之间存在这种不一致：qmake始终链接到发布Qt的版本，而如果构建类型为debug，则CMake将链接到Qt的调试版本。

要演示的小型项目

one.cpp

#include <QApplication>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    return app.exec();
}

one.pro

TEMPLATE += app
CONFIG += debug
QT += core gui widgets
SOURCES += one.cpp
TARGET = one

CMakeLists.txt

project(one)
set(CMAKE_BUILD_TYPE DEBUG)
set(CMAKE_MACOSX_RPATH 1)    
find_package(Qt5Core REQUIRED)
find_package(Qt5Gui REQUIRED)
find_package(Qt5Widgets REQUIRED)
add_executable(one MACOSX_BUNDLE one.cpp)
target_link_libraries(one Qt5::Core Qt5::Gui Qt5::Widgets)

比较两个版本：

使用qmake进行构建：

$ (mkdir build-qmake && cd build-qmake && ~/Qt/5.12.5/clang_64/bin/qmake .. && make)

$ otool -L build-qmake/one.app/Contents/MacOS/one
build-qmake/one.app/Contents/MacOS/one:
    @rpath/QtWidgets.framework/Versions/5/QtWidgets (compatibility version 5.12.0, current version 5.12.5)
    @rpath/QtGui.framework/Versions/5/QtGui (compatibility version 5.12.0, current version 5.12.5)
    @rpath/QtCore.framework/Versions/5/QtCore (compatibility version 5.12.0, current version 5.12.5)
    /System/Library/Frameworks/DiskArbitration.framework/Versions/A/DiskArbitration (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0)
    /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/AGL.framework/Versions/A/AGL (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.4)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.200.5)

使用CMake构建

$ (mkdir build-cmake && cd build-cmake && cmake .. && cmake --build .)

$ otool -L build-cmake/one.app/Contents/MacOS/one
build-cmake/one.app/Contents/MacOS/one:
    @rpath/QtWidgets.framework/Versions/5/QtWidgets_debug (compatibility version 5.12.0, current version 5.12.5)
    @rpath/QtGui.framework/Versions/5/QtGui_debug (compatibility version 5.12.0, current version 5.12.5)
    @rpath/QtCore.framework/Versions/5/QtCore_debug (compatibility version 5.12.0, current version 5.12.5)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.50.4)

^{（请注意，它链接到 _debug 版本）}

问题：尽管处于调试构建状态，如何使CMake与Qt版本链接？
