[CMake] Linux In-the-source Build multiple modes without swithing

[Dmytro Ovdiienko]

Charlie,

Move all your input data files to the resource folder and add following to
the end of CMakeLists.txt

######################################
# Post-build steps
######################################

add_custom_command(
    TARGET ${PROJECT_NAME}

    POST_BUILD
    COMMAND ${CMAKE_COMMAND} ARGS -E copy_directory
${${PROJECT_NAME}_SOURCE_DIR}/resources ${${PROJECT_NAME}_BINARY_DIR}
)

PROJECT_NAME is a variable that holds name of the target.

After all your executale files will work correctly from VS and on Linux.

BTW, how about to add to CMake posibility to create symbolic/hard links?
