[CMake] Reading settings from generated files

I am cross-compiling for an embedded platform and I have to use a
third-party tool which, depending on a per-project configuration file,
does the following:
- compiles a .o file with some init code
- generates a file containing a list of libraries to link against
- generates a file containing some compiler flags
I am quite happy to do this with ADD_CUSTOM_COMMAND, since the operation
is quite slow so I'd like to do that on make time, and also because the
third-party tool is automatically rerun if the configuration file changes.
Now, the question is: how do I read the generated files to set things
like CMAKE_C_FLAGS and LINK_DIRECTORIES after the custom command is
executed?
I could find no way to manipulate files after configuration time.
Best regards,
Andrea
