Could not find a package configuration file provided by "Qt5Core"

[sonn-gamm]

Hi,
this bug is specifically related to building Scribus on macOS with all the software installed through homebrew.

When running

cmake --debug-output ../scribus-indigo-master

from scribus/bin

I get the following error (tail)

CMake Error at CMakeLists.txt:604 (find_package):
  By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5Core", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5Core"
  (requested version 5.5.0) with any of the following names:

    Qt5CoreConfig.cmake
    qt5core-config.cmake

  Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set
  "Qt5Core_DIR" to a directory containing one of the above files.  If
  "Qt5Core" provides a separate development package or SDK, be sure it has
  been installed.

I tried to follow some of the suggestions shared here Qt5 Cmake Files Incorrect #29938 but without luck.

How do you correctly build Scribus on macOS?

Thanks,
af
