I'm writing a FooConfig.cmake to support
find_package(Foo COMPONENTS A B C)
I see that Foo_FOUND is always TRUE no matter what I try to set to from
FooConfig.cmake.
How does a FooConfig.cmake tell the caller whether the components were
all found?
I can make my own variables, but I wanted to know if there was an
official way to do this.
Thanks,
Clint
