[CMake] Why the ui_header.h can not be found in Qt project when I add a share lib?

[Kermit Mei]

Hello,I'm a novice for cmake. I'm trying to run a qt-project like this:

$ tree
.
|-- CMakeLists.txt
|-- build
|-- gui //I want creat a share lib here.
| |-- CMakeLists.txt
| |-- gotocelldialog.cpp
| |-- gotocelldialog.h
| `-- gotocelldialog.ui
`-- main.cpp

2 directories, 6 files



The CMakeLists.txt of the root is:
$ cat CMakeLists.txt

###################################
CMAKE_MINIMUM_REQUIRED(VERSION 2.6)
PROJECT( GTC )

ADD_SUBDIRECTORY( gui )

INCLUDE_DIRECTORIES(${GTC_SOURCE_DIR}/gui)
LINK_DIRECTORIES(${GTC_BINARY_DIR}/gui)

ADD_DEFINITIONS( -Wall )

FIND_PACKAGE( Qt4 REQUIRED )

INCLUDE( ${QT_USE_FILE} )

SET( GTC_SRCS main.cpp )

INCLUDE_DIRECTORIES( ${CMAKE_BINARY_DIR} )

ADD_EXECUTABLE( gtc ${GTC_SRCS} )
SET(EXECUTABLE_OUT_PATH ${CMAKE_BINARY_DIR})
TARGET_LINK_LIBRARIES( gtc GUI )
#############END###############





And the /gui/CMakeLists.txt is like this:
$ cat gui/CMakeLists.txt
###################################
SET( GUI_SRCS
gotocelldialog.cpp
)

SET( GUI_MOC_HDRS
gotocelldialog.h
)

SET( GUI_UIS
gotocelldialog.ui
)

ADD_DEFINITIONS( -Wall )

FIND_PACKAGE( Qt4 REQUIRED )

INCLUDE( ${QT_USE_FILE} )

QT4_WRAP_UI( GUI_UI_HDRS ${SAMPLE_UIS} )

QT4_WRAP_CPP( GUI_MOC_SRCS ${GUI_MOC_HDRS} )

INCLUDE_DIRECTORIES( ${CMAKE_BINARY_DIR} )

ADD_LIBRARY(GUI SHARED ${GUI_SRCS} ${GUI_MOC_SRCS} ${GUI_UI_HDRS} )
###########END##################


But, the "make" result is :

What's wrong with it? The source code is correct, and I can use qmake to
compile and run it.

Thank you, very muck!
