Yeah, thought so. I tried to move it behind the options which end at line
250 something. But then I get this error instead:

CMake Error at development/cmake/modules/FindQt4.cmake:1037 (message):
  Qt qmake not found!
Call Stack (most recent call first):
  CMakeLists.txt:813 (find_package)

and GNUWIN32_DIR is not asked, I put:

message(STATUS "GNUWIN32_DIR: ${GNUWIN32_DIR}")

right after that include and it shows:

GNUWIN32_DIR:

so the variable is empty, but CMake doesn't output an error and it also
doesn't show this variable in the GUI.
