Can't actually build with different build directory as suggested

[315234]

Build fails when building in a separate directory since the compiler cannot find config.h

[rizsotto]

thanks for the report. i need some more information in order to help you.

• what OS/distro?
• what CMake version?
• commands (and their outputs) you've executed after git clone?

[rizsotto]

thanks!
unfortunately i don't have any access to OSX systems.
and i do build this code in a separate build directory since i started this project.
so, can't really reproduce the issue.

[breser]

I'll take a look at it.

[rizsotto]

Ben, that would be wonderful! :)

[breser]

Your cmake command should be:
cmake ..

[breser]

I am however seeing a different problem on OS X.

[315234]

I can build with cmake ... Sorry for the noise.

[rizsotto]

thanks guys! i'm closing this ticket then...
Ben, you got a good eyes, i did not catch the '../src' :)

and please report the problem what you see (there is another open ticket for OSX already. ;))
