[petsc-dev] CMake-assisted CUDA builds ready

[Karl Rupp]

Hi Jose,

No need to send the logs, I can see the problem: Something is going 
wrong when dealing with double-quotes.
The flag string

  --compiler-options 
,\"-fPIC\",\"-Wall\",\"-Wwrite-strings\",\"-Wno-strict-aliasing\",\"-Wno-unknown-pragmas\",\"-O\"

gets passed through BuildSystem, which tries to put double quotes around 
it. This leads to

  " --compiler-options 
,"-fPIC\",\"-Wall\",\"-Wwrite-strings\",\"-Wno-strict-aliasing\",\"-Wno-unknown-pragmas\",\"-O\" 
\"

instead of

  " --compiler-options 
,\"-fPIC\",\"-Wall\",\"-Wwrite-strings\",\"-Wno-strict-aliasing\",\"-Wno-unknown-pragmas\",\"-O\" 
"

and thus the compiler complains. For some reasons the issue does not 
show up on my machine, even though I have the same versions of CMake and 
CUDA. I'll try to track it down.

Best regards,
Karli
