correct
which requires the generation an executable file first.

DETAILS: as requested:
add_executable(BouncyBall BouncyBall.c)
find_library(OLD_LIBRARY OLD)
target_link_libraries(BouncyBall ${OLD_LIBRARY})
COMMAND(./BouncyBall > my_BouncyBall.out
- diff BouncyBall.out my_BouncyBall.out)
what is needed:-
a) syntax for generating BouncyBall executable with oppropriate linking to
${OLD_LIBRARY}
b) syntax within cmake for executing BouncyBall executable and diffing
output to 'existing' outputfile
i.e this bit:-
(
COMMAND(./BouncyBall > my_BouncyBall.out
- diff BouncyBall.out my_BouncyBall.out )
)
I hope I did provide the example unix Makefile that is being translated.
thanks
and
regards
