If the user does not trust find_library for checking proper extension then:
1) He could modify/append CMAKE_FIND_LIBRARY_SUFFIXES
in this case:
list(APPEND CMAKE_FIND_LIBRARY_SUFFIXES ".so.2")
should work.
2) He could use find_file
Now if we consider this is a bug,
then with your modification "HasValidSuffix" is ill-named since it is more like
"ContainsValidSuffix" or "MatchesValidSuffix".
With this modification one could now find a not-properly-installed
library (missing links)
without noticing it.
What is your purpose here, do you want to ensure that you find a
particular version of a lib?
