c++ - full - Cómo encontrar el módulo Qt5 CMake en Windows
qt full (5)
Añadir esto resuelve el problema.
set (CMAKE_PREFIX_PATH "C://Qt//Qt5.0.1//5.0.1//msvc2010//")
Edité el primer post.
Estoy tratando de hacer una aplicación Qt5 muy básica usando CMake en Windows. Usé la documentación de Qt5 para usar CMake , y mi archivo main.cpp
solo contiene una función main
.
Mi CMakeLists.txt
es exactamente:
cmake_minimum_required(VERSION 2.8.9)
project(testproject)
Solución EDIT
set (CMAKE_PREFIX_PATH "C://Qt//Qt5.0.1//5.0.1//msvc2010//")
finalizar EDIT
# Find includes in corresponding build directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)
# Instruct CMake to run moc automatically when needed.
set(CMAKE_AUTOMOC ON)
# Find the QtWidgets library
find_package(Qt5Widgets)
# Tell CMake to create the helloworld executable
add_executable(helloworld hello.cpp)
# Use the Widgets module from Qt 5.
qt5_use_modules(helloworld Widgets)
Cuando en MSysGit bash, escribo `$ cmake -G" Visual Studio 11 "
Obtengo esta salida:
$ cmake -G"Visual Studio 11"

CMake Warning at CMakeLists.txt:11 (find_package):
By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"Qt5Widgets", but CMake did not find one.
Could not find a package configuration file provided by "Qt5Widgets" with
any of the following names:
Qt5WidgetsConfig.cmake
qt5widgets-config.cmake
Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set
"Qt5Widgets_DIR" to a directory containing one of the above files. If
"Qt5Widgets" provides a separate development package or SDK, be sure it has
been installed.
CMake Error at CMakeLists.txt:17 (qt5_use_modules):
Unknown CMake command "qt5_use_modules".
-- Configuring incomplete, errors occurred!
¿Tienes alguna idea?
Aquí hay una técnica que aprovecha la capacidad de cmake de leer el registro para forzar a un valor de registro a ubicar el Qt5Config.cmake del Qt5Config.cmake
.
Intenta usar la versión más alta de Qt5 disponible haciendo una ordenación inversa en los diferentes nombres de carpeta "5.x" que se encuentran dentro (por ejemplo, C:/Qt/
).
Esto también podría colocarse dentro de un módulo, por ejemplo, QtLocator.cmake
.
SET(QT_MISSING True)
# msvc only; mingw will need different logic
IF(MSVC)
# look for user-registry pointing to qtcreator
GET_FILENAME_COMPONENT(QT_BIN [HKEY_CURRENT_USER//Software//Classes//Applications//QtProject.QtCreator.cpp//shell//Open//Command] PATH)
# get root path so we can search for 5.3, 5.4, 5.5, etc
STRING(REPLACE "/Tools" ";" QT_BIN "${QT_BIN}")
LIST(GET QT_BIN 0 QT_BIN)
FILE(GLOB QT_VERSIONS "${QT_BIN}/5.*")
LIST(SORT QT_VERSIONS)
# assume the latest version will be last alphabetically
LIST(REVERSE QT_VERSIONS)
LIST(GET QT_VERSIONS 0 QT_VERSION)
# fix any double slashes which seem to be common
STRING(REPLACE "//" "/" QT_VERSION "${QT_VERSION}")
# do some math trickery to guess folder
# - qt uses (e.g.) "msvc2012"
# - cmake uses (e.g.) "1800"
# - see also https://cmake.org/cmake/help/v3.0/variable/MSVC_VERSION.html
MATH(EXPR QT_MSVC "2000 + (${MSVC_VERSION} - 600) / 100")
# check for 64-bit os
# may need to be removed for older compilers as it wasn''t always offered
IF(CMAKE_SYSTEM_PROCESSOR MATCHES 64)
SET(QT_MSVC "${QT_MSVC}_64")
ENDIF()
SET(QT_PATH "${QT_VERSION}/msvc${QT_MSVC}")
SET(QT_MISSING False)
ENDIF()
# use Qt_DIR approach so you can find Qt after cmake has been invoked
IF(NOT QT_MISSING)
MESSAGE("-- Qt found: ${QT_PATH}")
SET(Qt5_DIR "${QT_PATH}/lib/cmake/Qt5/")
SET(Qt5Test_DIR "${QT_PATH}/lib/cmake/Qt5Test")
ENDIF()
Y entonces..
# finally, use Qt5 + COMPONENTS technique, compatible with Qt_DIR
FIND_PACKAGE(Qt5 COMPONENTS Core Gui Widgets Xml REQUIRED)
Debería establecer la variable de entorno CMAKE_PREFIX_PATH en su lugar o usar cmake-gui para establecer la ruta de los paquetes Qt 5.
Solo necesita agregar la ruta Qt a la variable Windows% PATH%. Como se sugiere en la documentación oficial: http://doc.qt.io/qt-4.8/install-win.html#step-3-set-the-environment-variables
Una forma es abrir CMakeLists.txt en Qt Creator. Qt Creator admite CMake de forma nativa y siempre sabe dónde está Qt.
