Summary

0011034: ExternalProject reports "keyword undefined" when the SOURCE_DIR begins with 3 UpperCase letters

Description

In the ExternalProject.cmake:

function(_ep_parse_arguments f name ns args)
...
156 # We loop through ARGN and consider the namespace starting with an
157 # upper-case letter followed by at least two more upper-case letters
158 # or underscores to be keywords.
...
161 foreach(arg IN LISTS args)
...
164 if(arg MATCHES "^[A-Z][A-Z0-9_][A-Z0-9_]+$" AND
...
175 message(AUTHOR_WARNING "unknown ${f} keyword: ${arg}")
...

As mentioned in the comments and implemented in line 164, a typical use case of ExternalProject_Add for ITK, VTK, CTK, ... produces the error "unknown ITK keyword:" etc.

ExternalProject_Add( CTK
    SOURCE_DIR CTK
    BINARY_DIR CTK-Build

ExternalProject_Add( ITK
    SOURCE_DIR ITK

ExternalProject_Add( ITK
    SOURCE_DIR ITK

Instead you have to do

ExternalProject_Add( ITK
    SOURCE_DIR ${AN_EXTA_PATH_VAR}/ITK

Which somewhat defeats the use of a base_path.

I escalated to Major since the error message is unhelpful. You've got to look at the code to figure out what is going on.
