使用CMake编译Qt Qml程序,出现find_package 错误

 在使用CMake编译Qt 项目的时候,出现了一下错误。  记录一下解决方案,避免以后出现类似的问题。

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake:28 (find_package):
  Could not find a package configuration file provided by "Qt5Quick" with any
  of the following names:

    Qt5QuickConfig.cmake
    qt5quick-config.cmake

  Add the installation prefix of "Qt5Quick" to CMAKE_PREFIX_PATH or set
  "Qt5Quick_DIR" to a directory containing one of the above files.  If
  "Qt5Quick" provides a separate development package or SDK, be sure it has
  been installed.
Call Stack (most recent call first):
  Application/CMakeLists.txt:5 (find_package)


-- Configuring incomplete, errors occurred!

解决方案:

1.找到Qt5 cmake 所在的目录

/home/ubuntu/tools/Qt5.12.0/5.12.0/gcc_64/lib/cmake

发现,我的电脑Qt钟cmake所在的目录,如上所示

2.添加编译选项解决如山问题

cmake -DCMAKE_PREFIX_PATH=/home/ubuntu/tools/Qt5.12.0/5.12.0/gcc_64/lib/cmake  ..
set(CMAKE_PREFIX_PATH "/home/ubuntu/tools/Qt5.12.0/5.12.0/gcc_64/lib/cmake")

经过以上步骤,可以完美解决。

如果还出现如上错误, 那么,就需要检查下,对应的包是否存在,  如果不存在, 那么就需要安装全部的包。
