Description:
I tried to compile attica on 32bit with `yaourt -Sb attica`. This seem to fail on missing qt-dependency.

Additional info:
* package version(s)
attica 0.4.2-1
* config and/or log files etc.

CMake Error at CMakeLists.txt:12 (find_package):
By not providing "FindQt5Transitional.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"Qt5Transitional", but CMake did not find one.

Could not find a package configuration file provided by "Qt5Transitional"
with any of the following names:

Qt5TransitionalConfig.cmake
qt5transitional-config.cmake

Add the installation prefix of "Qt5Transitional" to CMAKE_PREFIX_PATH or
set "Qt5Transitional_DIR" to a directory containing one of the above files.
If "Qt5Transitional" provides a separate development package or SDK, be
sure it has been installed.


Steps to reproduce:
Do run `yaourt -Sb attica` on a clean system with just basic files and a Gnome on it.
