OK, that settled then, I'll create my on taget my_all or something
like that then :-)

Yes I get the following error:

$ make complete
[100%] Built target bar
[100%] Built target extras
make[3]: *** No rule to make target `extras', needed by
`CMakeFiles/complete'.  Stop.
make[2]: *** [CMakeFiles/complete.dir/all] Error 2
make[1]: *** [CMakeFiles/complete.dir/rule] Error 2
make: *** [complete] Error 2


With this CMakeLists.txt file:

PROJECT (tester)
CMAKE_MINIMUM_REQUIRED (VERSION 2.6)
CMAKE_POLICY (VERSION 2.6)

add_executable(bar
        bar.c
)
add_custom_target(extras
        DEPENDS bar
)
add_custom_target(complete
        DEPENDS extras
)


I've tried to look into the makefiles but could not find the solution.

I have included the verbose output of make at the end of this mail

It seems that the file CMakeFiles/complete.dir/build.make references
the extras target that is defined in CMakeFiles/extras.dir/build.make

Probably a bug. Will report it later.
