It all depends on how you use the values.  Typical CMake convention is this:

PROJECT_INCLUDE_PATH -> include_directories(${PROJECT_INCLUDE_PATH})

PROJECT_LIBRARY (full path to the library) -> target_link_libraries(target
${PROJECT_LIBRARY})

Libraries are typically encoded with the full path.  This is largely due to
how libraries are found in CMake.  When you search for a library you do the
following which produces the full path to the library.

find_library(PROJECT_LIBRARY name <paths to search>)

PROJECT_LIBRARY then has the full path to the library.  When you feed the
full path of the library to CMake it can be sure that this library and no
other library will be used.  You could compute the directory where the
library is (using various techniques which I won't go into here), and then
add the link path:

link_directories(${PROJECT_LIBRARY_DIR})
target_link_libraries(target library_name)

This method is less preferred to the full path to the library, because
technically you can pick up a different library if another exists in the
link path before the one you want.

If your project has multiple libraries a helper variable is usually created:

set(PROJECT_LIBRARIES ${PROJECT_LIB_A_LIBRARY} ${PROJECT_LIB_B_LIBRARY})
...
target_link_libraries(target ${PROJECT_LIBRARIES})
