[Cmake] Running a different program for the linker (purify on sun)

[Bill Hoffman]

The way to run an extra program in front of the link line,
is to change the rule variable CMAKE_CXX_LINK_EXECUTABLE,
and CMAKE_C_LINK_EXECUTABLE.   The values for these
variables can be found in Modules/CMakeDefaultMakeRuleVariables.cmake,
and are sometimes redefined in Modules/Platform/*.cmake.  Make
sure it is set after the PROJECT comamand.

Here is a small example:

PROJECT(foo)

SET(CMAKE_CXX_LINK_EXECUTABLE
    "purify <CMAKE_CXX_COMPILER> <CMAKE_CXX_LINK_FLAGS> <LINK_FLAGS> <FLAGS> <OBJECTS>  -o <TARGET> <LINK_LIBRARIES>")
ADD_EXECUTABLE(foo foo.cxx)


Of course, for a real CMakeLists.txt file you should have some IF checks
for the correct platform, this will only work for the makefile generators, the
rule variables are not used by the IDE generators.
