daze -- uic not found with cmake-3.13

Hi there

Trying to build zeal [1] with cmake 3.13 on FreeBSD fails with uic not being found:

CMake Error: AutoUic (Registry): The uic executable "" does not exist

A complete build log can be found here [2]. This seems to be a regression in 3.13, as it worked with 3.12.x.
