ok. really fix by toggling back to ready. At least, I think this should do it...
set(QT_USE_QTCORE TRUE)
find_package(Qt4 REQUIRED)
include(${QT_USE_FILE})
file(GLOB SRCS "*.c" "*.cpp")
file(GLOB PUBLIC_HEADERS "*.h")
qt4_wrap_cpp(MOC_SRCS "quazipfile.h")
set(SRCS ${SRCS} ${MOC_SRCS})
add_library(quazip STATIC ${SRCS})
