Not sure I understood you correctly, but it works very naturally in
CMake. If your target foo (say, an executable) links with library bar
(i.e. has bar in target_link_libraries) and there happens to be a bar
library in the source tree, CMake will build bar and link foo with it
automatically. Furthermore, if bar is a static library and it itself
depends on other libraries, CMake will build and add those to the foo
linking command line.
