Make it easier to use libdlt when building DLT as a CMake subproject (#254)
By calling target_include_directories() for the dlt target in src/lib/.
CMake filters out duplicate include paths. So even if the include
directories are already added with include_directories() in the top-level
CMakeLists.txt, they are not duplicated when the compiler is invoked.
For example, with this patch, the following works:
[~/Source/foo]$ ls
bar CMakeLists.txt dlt-daemon
[~/Source/foo]$ cat CMakeLists.txt
cmake_minimum_required(VERSION 3.3 FATAL_ERROR)
project(foo)
add_subdirectory(dlt-daemon)
add_subdirectory(bar)
[~/Source/foo]$ cat bar/CMakeLists.txt
cmake_minimum_required(VERSION 3.3 FATAL_ERROR)
project(bar)
add_executable(bar main.cpp)
target_link_libraries(bar dlt)
install(TARGETS bar RUNTIME DESTINATION bin)
bar/main.cpp contains the example from the top of
doc/dlt_for_developers.md that does "#include <dlt.h>" and then uses the
DLT logging macros.
