The CMake code previously expected CMAKE_SOURCE_DIR to point to the root of the libfranka source tree, which is not true when libfranka is added to a project using add_subdirectory().
In the issue #67 I initially suggested using the variable CMAKE_CURRENT_LIST_DIR, but afterwards I decided to use CMAKE_CURRENT_SOURCE_DIR for consistency with existing code in libfranka.
