ExternalProject: Add EXCLUDE_FROM_ALL option to ExternalProject_Add 

When adding a new external project, the "all" target will depend on
this.
This option allows one to add an external project will not be executed
when the "all" target is executed.
The reason for this is that an external project could be useful, for
example, only for running tests, and therefore not necessary during
the build.
