Hello, I am a beginner on ROS and now trying a project which contains hector_slam package in WIN10. The build fails since I don't have QT4, I know that Melodic is now using Qt 5 and Ubuntu user can just install Qt 4 by running using sudo apt install qt4-default (see "version issue" for hector_slam in github).

As a Windows user, how could fix it or install Qt 4.

Error Details:

-- +++ processing catkin package: 'hector_geotiff'

-- ==> add_subdirectory(hector_slam/hector_geotiff)

-- Using these message generators: gencpp;geneus;genlisp;gennodejs;genpy CMake Error at C:/opt/python27amd64/Lib/site-packages/cmake/data/share/cmake-3.15/Modules/FindQt4.cmake:1314 (message):

Found unsuitable Qt version "5.10.1" from C:/opt/rosdeps/x64/bin/qmake.exe, this code requires Qt 4.x

Call Stack (most recent call first): hector_slam/hector_geotiff/CMakeLists.txt:12 (find_package)

Thanks for your answer. After I replace the components name in CMakeLists file for the error part in Hector from find_package(Qt4 4.6 COMPONENTS QtCore QtGui REQUIRED) to find_package(Qt5 COMPONENTS Core Gui REQUIRED) the error disappear, but not sure will it work correct actually since I still have some other errors for the project. I will try Cartographer if Hector cannot work.
