There is no way to do this. C/C++ targets (executables and libraries)
suffer from the same problem: if you set
CMAKE_SKIP_INSTALL_ALL_DEPENDENCY and then run "make install" without
running "make" first, the install rule will complain that it can't find
the files (such as libfoo.a.) If you set
CMAKE_SKIP_INSTALL_ALL_DEPENDENCY, you have to make sure the targets
you want to install are built before running "make install".
