I'm still seeing this behavior with CMake 3.4.1. Here's a friendlier
plaintext representation of the previous htop screenshot snippet:

ninja -l3
└── /usr/bin/ninja-build
├── /usr/bin/ninja-build
└── /usr/bin/ninja-build

Is this expected behavior, a known bug, or a new bug that I should file?
Note that this example shows the -l option not being propagated, but I
think all of the following Ninja options should be propagated:

  -l N do not start new jobs if the load average is greater than N
  -n   dry run (don't run commands but act like they succeeded)
  -v   show all command lines while building
  -d stats print operation counts/timing info
  -d explain   explain what caused a command to execute
  -t clean clean built files
  -t commands  list all commands required to rebuild given targets

Thanks,
Taylor

[CMake] ninja command line options not propagated to ninja invocation for superbuild projects

[Taylor Braun-Jones]

See htop screenshot below for an example of what I mean. Note that `ninja`
in the original command line invocation is just a bash alias for
ninja-build (the name of the ninja binary on Fedora-based systems)

Should I expect to see the -l3 option to be propagated automatically to the
sub projects of my superbuild? Or do I need to do some special cmake
configuration to make this happen? Or is this just a known issue?

Thanks,
