can cmake start the build?

Dietmar Hummel-3
Hi everybody!

I searched around but could not find the solution. My question is, is there a
option in cmake to actually start the build.
If i execute cmake with --system-information it shows me in the variable
CMAKE_BUILD_TOOL the correct program to start the build. As you know this is
make on unix systems but devenv or something else on windows.

So is there anything like

cmake funny_start_the_build_parameter [maybe some params]

to do just the right thing on each os?

Regards
Dietmar

If what you want is to trigger configuration+build(+install) with one single call, cmake already does something similar to what you want. On an already configured project (you need to call cmake explicitly at least once), when you invoke make (or equivalent), cmake will be automatically called if configuration needs to be rerun.

Option 2: Write a small script that invokes cmake, then make

I don't know if you can do exactly what you want, because Makefiles (or equivalent) are not generated until the very end of the configuration process.

Just curious, why do you need to _always_ trigger the build after configuring?

HTH,

Adolfo

cmake from cvs HEAD gives this:
$ cmake --help
...
  --build <dir>               = Build a CMake-generated project binary tree.
...

Did you try this ?
