[CMake] Making with purify

[William A. Hoffman]

Your right.  It is broken.  It would only work with a SUBDIR.
I am thinking something like this:

SET(CMAKE_PURIFY_LINK_C  "purify ${CMAKE_C_LINK_EXECUTABLE}")
SET_TARGET_PROPERTIES(my_exe.purify PROPERTIES LINK_RULE CMAKE_PURIFY_LINK_C )

Basically, allow the user to change the rule variable used for linking a target
via a property on the target.

But I get 2 binaries and they are both built with purify. Perhaps I made a mistake.  Your example does not include any TARGET_LINK_LIBRARIES() commands.  I assume I need one for each binary.
