How to rename Target Executable using CMake in Qt6?

[Kevin470]

Is there a possibility to rename my Executable file created through CMake for Qt6 ?
In QMake, I believe if the TARGET is renamed in the .pro file, the build creates an executable with that name. Is there a similar method in CMake?

Thanks.

Just change the name of the target (the first argument you pass to add_executable)

@VRonin Thank you for your response.

This is the CMake code I have:

cmake_minimum_required(VERSION 3.5)

project(ProjectName1 VERSION 0.1 LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets)
find_package(Qt6 REQUIRED COMPONENTS SerialPort)

set(PROJECT_SOURCES
        main.cpp
        mainwindow.cpp
        mainwindow.h
        mainwindow.ui
        serialComm.h
        serialComm.cpp
)

if(${QT_VERSION_MAJOR} GREATER_EQUAL 6)
    qt_add_executable(ProjectName1
        MANUAL_FINALIZATION
        ${PROJECT_SOURCES}
    )
# Define target properties for Android with Qt 6 as:
#    set_property(TARGET ProjectName1 APPEND PROPERTY QT_ANDROID_PACKAGE_SOURCE_DIR
#                 ${CMAKE_CURRENT_SOURCE_DIR}/android)
# For more information, see https://doc.qt.io/qt-6/qt-add-executable.html#target-creation
else()
    if(ANDROID)
        add_library(ProjectName1 SHARED
            ${PROJECT_SOURCES}
        )
# Define properties for Android with Qt 5 after find_package() calls as:
#    set(ANDROID_PACKAGE_SOURCE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/android")
    else()
        add_executable(ProjectName1
            ${PROJECT_SOURCES}
        )
    endif()
endif()

target_link_libraries(ProjectName1 PRIVATE
    Qt${QT_VERSION_MAJOR}::Widgets
    Qt::SerialPort)

set_target_properties(ProjectName1 PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

if(QT_VERSION_MAJOR EQUAL 6)
    qt_finalize_executable(ProjectName1)
endif()

If I change the argument to qt_add_executable from ProjectName1 to ProjectName2, I get an error building the CMake file. It says - "Cannot specify link libraries for target "ProjectName1" which is not built by this project."

And if I edit the argument for add_executable under if(!ANDROID), it builds under the old name.

Is there some information that I am missing?

Yes, how targets work in CMake. In what you posted above, however, everything is straightforward. Just do a find-and-replace for all instances of ProjectName1 to ProjectName2
