The source and header files will not magically be found in other 
directories.  You have to tell CMake where to find them.  Try this in 
the top-level CMakeLists.txt file:

ADD_LIBRARY(mylib src/x.cpp incl/x.hpp)
SOURCE_GROUP("Include Files" FILES incl/x.hpp)

Basically source files have to be named with a relative path to the 
location of the CMakeLists.txt file.  This may also work from 
lib/CMakeLists.txt:

ADD_LIBRARY(mylib ../src/x.cpp ../incl/x.hpp)
SOURCE_GROUP("Include Files" FILES ../incl/x.hpp)
