Question

当我使用以下代码时：

find_package(Qt5Widgets REQUIRED)
add_executable(ex ex.cc)
target_link_libraries(ex Qt5::Widgets Qt5::DBus)

我明白了：

Error: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:

我的qtbase路径位于＆＃34; / media / roroco / disk750 / Downloads / qt5 / qtbase＆＃34;，我编译了它，如何在find_package

中具体说明这条路径

Answer 1

    IF(CMAKE_SIZEOF_VOID_P EQUAL 8)
        SET(CMAKE_PREFIX_PATH $ENV{QT64_LOCATION})
        message(STATUS "QT find path: $ENV{QT64_LOCATION}")
    ELSE()
        SET(CMAKE_PREFIX_PATH $ENV{QT_LOCATION})
        message(STATUS "QT find path: $ENV{QT_LOCATION}")
    ENDIF()

并将路径添加到环境变量（如果未定义或硬编码） - CMAKE_PREFIX_PATH“C：\ Qt \ .. \ msvc2010 \”或Linux中的qmake路径即“/ media / roroco / disk750 / Downloads / qt5 / bin / qmake”

您也可以设置默认的qt路径

    /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf

将其设置为/ media / roroco / disk750 / Downloads / qt5 / bin /

Answer 2

将CMAKE_PREFIX_PATH设置为Qt文件夹。例如：

SET(CMAKE_PREFIX_PATH "C:/Qt/5.5/msvc2013")

根据您的操作系统，路径可能会有所不同。
