deepin linux下解决Qt搜狗输入法无法输入中文

网上很多方法都是把系统库下的libfcitxplatforminputcontextplugin.so复制到qt的目录下，但我的没效果。
我的QT版本为Qt5.14.1
下面是编译安装的方法。

正确的安装步骤

• 下载源码fcitx-qt5的源码
  git clone https://github/fcitx/fcitx-qt5
• 安装依赖
  sudo apt install cmake fcitx-libs-dev extra-cmake-modules libxkbcommon-dev
• 将qt的工具链加入PATH变量(这一步的目录大家可能不一样)
  export PATH=$PATH:/home/leon/Qt5.14.1/5.14.1/gcc_64/bin
• 开始编译
  cd fcitx-qt5
cmake .
make
sudo make install
• 复制
  cp /home/leon/Qt5.14.1/5.14.1/gcc_64/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so /home/leon/Qt5.14.1/Tools/QtCreator/lib/Qt/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so

遇到错误解决（下面是踩坑步骤）

cmake错误1 – ECMConfig.cmake

CMake Error at CMakeLists.txt:8 (find_package):
  Could not find a package configuration file provided by "ECM" (requested
  version 1.4.0) with any of the following names:

    ECMConfig.cmake
    ecm-config.cmake

  Add the installation prefix of "ECM" to CMAKE_PREFIX_PATH or set "ECM_DIR"
  to a directory containing one of the above files.  If "ECM" provides a
  separate development package or SDK, be sure it has been installed.

-- Configuring incomplete, errors occurred!

解决办法，装软件
sudo apt install extra-cmake-modules

错误2 – Qt5Config.cmake

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.

解决办法：没有配置qt工具的环境变量
export PATH=$PATH:/home/leon/Qt5.14.1/5.14.1/gcc_64/bin

错误3–XKBCommon

-- Could NOT find XKBCommon_XKBCommon (missing: XKBCommon_XKBCommon_LIBRARY XKBCommon_XKBCommon_INCLUDE_DIR) 
CMake Error at /usr/share/cmake-3.9/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

解决办法，装库
sudo apt-get install libxkbcommon-dev
