Attached are 3 CMake modules I use for this. One is a macro that
builds a batch file that ends up being a target in visual studio.

I put them in a CMake folder inside my root source folder and have the
following line in my main CMakeLists.txt

include(${PROJECT_SOURCE_DIR}/CMake/GetRuntime.cmake)

this brings in the macro with support for generating the batch file
and GetRuntime target.

Then later in the main CMakeLists.txt file I use the other two modules.

FIND_PACKAGE( Qt4 REQUIRED )
set(QT_USE_QTNETWORK true)
set(QT_USE_QTSQL true)
set(QT_USE_QTXML true)
INCLUDE( ${QT_USE_FILE} )
include(${PROJECT_SOURCE_DIR}/CMake/GetQtRuntime.cmake)
	
IF(USE_QWT)
FIND_PACKAGE(Qwt REQUIRED)
INCLUDE_DIRECTORIES(${QWT_INCLUDE_DIR})
include(${PROJECT_SOURCE_DIR}/CMake/GetQwtRuntime.cmake)
set (UPMC_EXTERNAL_LIBS ${UPMC_EXTERNAL_LIBS} ${QWT_LIBRARIES})
ENDIF(USE_QWT)
