I have migrated from Qt4 to Qt5 with CMake and found my way with [1] and
[2]:
----
find_package(Qt5 REQUIRED COMPONENTS Core Gui Widgets LinguistTools)

# Use the ones you need
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTORCC ON)

# LinguistTools is needed in find_package to make this macro available
qt5_create_translation(QM_FILES ${SRC_FILES} ${HEADER_FILES} ${UI_FILES}
${TS_FILES})

add_executable(PROGRAM ${SRC_FILES} ${HEADER_FILES} ${QM_FILES}
${QRC_FILES} ${UI_FILES})
target_link_libraries(PROGRAM Qt5::Core Qt5::Widgets Qt5::Gui)
-----

AUTOMOC inspect cpp source files to find Q_OBJECT or Q_GADGET.
AUTOUIC inspect cpp source files for #include of "ui_*.h" and the
existence of a .ui file to run uic on them.
AUTORCC run rcc on *.qrc sources files
