Hi.
I'm trying to compile WSJT-X from scratch, using the latest source tarball. I'm getting a compile error:
CMake Error at CMakeLists.txt:867 (find_package):
By not providing "FindQt5Multimedia.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"Qt5Multimedia", but CMake did not find one.

Could not find a package configuration file provided by "Qt5Multimedia"
(requested version 5) with any of the following names:

Qt5MultimediaConfig.cmake
qt5multimedia-config.cmake

Add the installation prefix of "Qt5Multimedia" to CMAKE_PREFIX_PATH or set
"Qt5Multimedia_DIR" to a directory containing one of the above files. If
"Qt5Multimedia" provides a separate development package or SDK, be sure it
has been installed.

Does anyone know what Ubuntu package I need to install to fix this error? I've googled for over an hour and cannot find it.

Thanks in advance.
