cmake-improvements (#135)

1. Allow building as a subproject of another
cmake project (CMAKE_* vs PROJECT_* variables)

2. Do not generate header files within source – bad practice, use build
directory for that(e.g. change location where dlt_version.h is being generated)

3. Use add_compile_options() instead of *_C/CXX_FLAGS variables for proper
compile environment definition, also bad practice, also see p.2

4. Add WITH_DLT_PKGCONFIG – add generate pkgconfig .pc files as switchable
option, should probably be part of headers install routine.
