quite simply, e.g.:

foo/CMakeLists.txt:
###################

PROJECT(foo) # project name

ADD_SUBDIRECTORY( vendor/bar ) # add subdir

INCLUDE_DIRECTORIES( include vendor/bar/include ) # add to include path

ADD_EXECUTABLE(
   foo                                          # build executable foo
   src/source1.cpp                   # from these sources
   src/source2.cpp
   src/component_x/source_x.cpp
)

TARGET_LINK_LIBRARIES(
   foo                            # to foo link
   bar                           # library bar which is in vendor/bar
)

###################


vendor/bar/CMakeLists.txt
###################

PROJECT( bar) # if you want to

INCLUDE_DIRECTORIES( include )

ADD_LIBRARY(
   bar
   src/source1.cpp
)

###################
