That's what I thought, but that property is not currently exported, right?
Are you thinking of in-tree cases, not exported cases? Or are you thinking
of config files like this:
include(FooTargets.cmake)
set_property(TARGET Foo::foo
PROPERTY MAP_IMPORTED_CONFIG_COVERAGE Release
)
?

Well, the evaluation process, yes, probably.

I'm not familiar with scheme.
I'm not certain what you mean by the 'entire' expression? If you mean the
whole string that gets passed to cmGeneratorExpression::Parse, the config is
already 'bound' for the entire evaluation of the expression (in
cmCompiledGeneratorExpression::Evaluate). So, I'm not certain what you mean
here.
Thanks,
Steve.
