hi all,
i'm trying to obtain the include paths from a target via a generator
expression, which is adapted from the help file:
help:
$<$<BOOL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>>:-I$<JOIN:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,
-I>>
i adapted it to obtain the value from a target, which is passed as a
function argument:
$<$<BOOL:$<TARGET_PROPERTY:${TARGET},INCLUDE_DIRECTORIES>>:-I$<JOIN:$<TARGET_PROPERTY:${TARGET},INCLUDE_DIRECTORIES>,
-I>>
however evaluating the expression results in this command string:
$<1:-I$<JOIN:$ -I>>
is this a bug or a feature?
thanks a lot,
tim
