[CMake] Question about BundleUtilities

[David Cole]

This likely means that "otool -L" on libA is reporting "
/Users/engelm/bundle-test/install/MacOS/liblibB.dylib" as a dependent
library... If that's true, then why doesn't the library exist?

Do you build libA against a build tree including libB or against an install
tree of libB...?

Yes, that is basically the intended usage of BundleUtilities. It looks like
you are using it correctly. Errors are difficult to diagnose, though.....


HTH,
David
