Yes I [apparently wrongly] supposed

that
cmSystemTools::FindProgram("dpkg")

would find 'dpkg' iff:
find_program(DPKG_EXECUTABLE NAMES dpkg)
did find it...

Why is the result of this two commands differents?
Are there some env var that makes the behavior different?
Or may be the configure environement is different from
the test environment...
