CMake在Docker/Ubuntu 18.04中找不到Qt5LinguistTools

Question

我的简单Dockerfile:

FROM ubuntu:18.04
RUN apt update && apt upgrade -y
RUN apt install build-essential cmake qt5-default -y
RUN apt install qttools5-dev-tools -y

当我检查集装箱内的linguist时，它就在那里：

root@9087245330a7:/# which linguist
/usr/bin/linguist

但是当我在容器中配置我的应用程序时：

CMake Error at CMakeLists.txt:72 (find_package):
By not providing "FindQt5LinguistTools.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"Qt5LinguistTools", but CMake did not find one.
Could not find a package configuration file provided by "Qt5LinguistTools"
(requested version 5.5.1) with any of the following names:
Qt5LinguistToolsConfig.cmake
qt5linguisttools-config.cmake
Add the installation prefix of "Qt5LinguistTools" to CMAKE_PREFIX_PATH or
set "Qt5LinguistTools_DIR" to a directory containing one of the above
files.  If "Qt5LinguistTools" provides a separate development package or
SDK, be sure it has been installed.

发生了什么事？这在Ubuntu16.04上运行得很好。

问题是在Ubuntu 18.04+中，您需要同时安装qttools5-dev才能获得/usr/lib/x86_64-linux-gnu/cmake/Qt5LinguistTools/Qt5LinguistToolsConfig.cmake。
