[CMake] Making with purify

[William A. Hoffman]

Currently, there is no way to to make a target optionally part of the all build.
If you are just using make, you might be able to do something like this:

SET(CMAKE_CXX_LINK_EXECUTABLE "$(PURIFY) ${CMAKE_CXX_LINK_EXECUTABLE}")
ADD_EXECUTABLE(my_exe  etc...)

# to build a purified my_exe
rm my_exe
make PURIFY=purify 
# to build the regular my_exe
rm my_exe
make 

The $(PURIFY) variable will be treated as a make variable, and
will expand to nothing when you do not define it on the command line.
