same applies to 2.8.12.2.
the genex is:
$<$<BOOL:$<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>>:-I$<JOIN:$<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>,
-I>>
changing the genex to:
$<$<BOOL:$<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>>:-I$<JOIN:
$<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES> , -I>>
it expands to:
$<1:-I$<JOIN: /Users/tim/dev/x/a;/Users/tim/dev/x/b;/Users/tim/dev/x/c ,
-I>>
