Get SOURCES of Target

[Leon0402]

@ben.boeckel

The thing is that some sources cannot be known until generator time (e.g., genex conditionals), so any configure-time query will be insufficient for accurate behaviors.

Not even if I use a generator expression myself, so something like:

$<TARGET_PROPERTY:${target},SPECIFIED_SOURCES>

Is there like some order in which generator expressions are evaluated? So if I have:

target_sources(MyTarget $<...>)
$<TARGET_PROPERTY:${target},SPECIFIED_SOURCES>

Is it just the order in which they are, so the one in target sources is evaluated earlier?

@ben.boeckel

If that works, sure. I don’t know how paths returned from SOURCES report if they are added in different directories.

Based on some Tests SOURCES contain relative paths for the sources in the same directory of the target (so basically just the file names) and absolute path for any subdirectories.
Which is weird to be honest
I would expect all to be a relative path.
