[CMake] Interpretation of RUNTIME_OUTPUT_DIRECTORY in VisualStudio

[Michael Jackson]

try the following:
ADD_CUSTOM_TARGET(QtLibs
                                             COMMAND ${CMAKE_COMMAND} -E
copy_if_different ${CMAKE_CURRENT_SOURCE_DIR}/libQtCore.so.4
${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/${CMAKE_CFG_INTDIR}...)



	• CMAKE_CFG_INTDIR: Build time configuration directory for project.
This is a variable that is used to provide developers access to the  
intermediate directory used by Visual Studio IDE projects. For  
example, if building Debug all executables and libraries end up in a  
Debug directory. On UNIX systems this variable is set to ".". However,  
with Visual Studio this variable is set to $(IntDir). $(IntDir) is  
expanded by the IDE only. So this variable should only be used in  
custom commands that will be run during the build process. This  
variable should not be used directly in a CMake command. CMake has no  
way of knowing if Debug or Release will be picked by the IDE for a  
build type. If a program needs to know the directory it was built in,  
it can use CMAKE_INTDIR. CMAKE_INTDIR is a C/C++ preprocessor macro  
that is defined on the command line of the compiler. If it has a  
value, it will be the intermediate directory used to build the file.  
This way an executable or a library can find files that are located in  
the build directory.
