내가 설치 다음 누락 된 패키지 :

sudo apt-get install qtbase5-dev 
sudo apt-get install qtdeclarative5-dev

는 접두사의 종류는 이제 필요하지 않습니다 부착 :

:~/junk/qtquick_hello_cmake$ cat CMakeLists.txt 
    cmake_minimum_required(VERSION 2.8.12) 

    project(qtquick_hello_cmake) 

    set(CMAKE_INCLUDE_CURRENT_DIR ON) 
    set(CMAKE_AUTOMOC ON) 
    set(CMAKE_AUTORCC ON) 

    find_package(Qt5 COMPONENTS Quick Core REQUIRED) 

    qt5_add_resources(RESOURCES qml.qrc) 

    add_executable(${PROJECT_NAME} "main.cpp" "qml.qrc") 

    qt5_use_modules(${PROJECT_NAME} Quick Core) 

    target_link_libraries(${PROJECT_NAME} Qt5::Core Qt5::Quick) 


:~/junk/qtquick_hello_cmake$ ls 
build CMakeLists.txt main.cpp main.qml qml.qrc 

:~/junk/qtquick_hello_cmake$ cd build/ 
:~/junk/qtquick_hello_cmake/build$ rm -rf *

CMake 오류 메시지 find_package 실패 CMAKE_PREFIX_PATH 설정 변수

을 CMAKE_PREFIX_PATH하는 "Qt5"의 설치 접두사를 추가

은 오해의 소지가 있습니다. "설치 접두사"에 대해서만 말하지만,이 설치는 여전히 에 또는 qt5-config.cmake 파일을 포함해야합니다.이 파일은 find_package에 의해 검색 가능합니다.

그러나 메시지

"Qt5"는 별도의 개발 패키지 또는 SDK,이 설치되어 확인을 제공합니다.

는 분명하다 : 필요한 설정 파일을 포함하는 개발 패키지를 설치하는

하나가 필요합니다.

모든 위의 스크립트는 CMake으로도이 명령을 사용 CMake 프로젝트로도 제공되고, 때 "찾기"만 CONFIG find_package의 모드로 적용 할 수 있습니다.
