[CMake] reusing CMAKELISTS.txt

[Craig Scott]

You can re-use the same CMakeLists.txt with add_subdirectory as long as
each call specifies a different binary directory. Not saying this is a
particularly good design, but it is allowable. E.g.

# First time with a particular value of someVar
set(someVar 1234)
add_subdirectory(foo foo1)

# Do it again with a different someVar
set(someVar abcd)
add_subdirectory(foo foo2)


Instead of trying to re-use a whole CMakeLists.txt, consider defining a
function or macro instead and call that in the places where you want to
re-use the same code.
