We've done this with many projects.  We just create a project-specific
wrapper in the projects's own CMakeLists.txt files and then teach it
to invoke all the third-party helpers we want.

include(FancyMod1)
include(FancyMod2)
function(myproj_add_executable)
  add_executable(${ARGN})
  fm1_help_exe(${ARGN})
  fm2_help_exe(${ARGN})
endfunction()
