ExternalProject: Report error if local variables are not defined
Since in some situations, ExternalProject module may be included in
a sub-directory, functions will be available in the global scope but
local variables like "_ep_keywords_<keyword>" will not be defined, this
commit checks and reports an error indicating that the ExternalProject
module must be explicitly included before using any of the ExternalProject_*
functions that require the module's inclusion within the current scope
or above.
