commands executed out of order

[cbrown]

   I have encountered something funny with a rule like this;

meta-project.site:
        mkdir test-reports
        $(shell cp somefile.info test-reports/app.info)

   When this runs, I see this;

cp: cannot create regular file `app.info': No such file or directory
mkdir -p sbs/target/debug/test-reports

      I fixed the issue by removing the $(shell construct and just doing
the cp, but still; Why do the original commands execute out of order?
