[CMake] do not build in each dir anymore. No need. (#8494)

  - The CMake configuration setup has changed in #8485. Which means
    almost all targets are enabled by default and all of them are part
    of the `all` make target.

    So there is no need to go into each dir and issue installation. The
    fact that they are part of `all` means all of them will be built and
    installed.

    The excpetion is the `testsuite-depends` target which includes the
    targets:
      - libs-for-testing: installation of Modelica libs for testing.
      - reference-files: extraction of reference files.
