[CMake] Quick question: CMAKE_CXX_FLAGS vs CMAKE_CXX_COMPILE_FLAGS

2013-04-02 Thread Daniel Carrera
Hi everyone,

What is the difference between CMAKE_CXX_COMPILE_FLAGS and CMAKE_CXX_FLAGS?

The wiki only mentions CMAKE_CXX_FLAGS and CMAKE_C_FLAGS, and those
are clearly used for compiling. But if you Google for CMake examples
(e.g with MPI) you will quickly find CMake scripts that have
CMAKE_CXX_COMPILE_FLAGS.

I am experimenting with CMake and I want to figure out if I should be
using CMAKE_Fortran_FLAGS or CMAKE_Fortran_COMPILE_FLAGS.

Thanks for the help.

Cheers,
Daniel.

Hi,

I believe compile flags are *not* used during linking, while
CMAKE_CXX_FLAGS will also be used during linking (if your linker
language is C++). I do not know of any other differences, but perhaps an
expert wants to correct me..

Cheers,
Yngve
