This feature is not very, let's say polished, so yes, it is not perfect as it
is.
Why do you want do do this ?
How about adding a "my_find_library()", so you don't have to rename it ?
In KDE4 we have KDE4_ADD_EXECUTABLE(), KDE4_ADD_LIBRARY() which add some
features, and developers who want to make use of this have to use these
functions.
It works well for us.
