[petsc-dev] CMake: make, install, find_package ?

[Franck Houssen]

Here is a bundle you can pull for you to have a look (franck/cmake branch - push KO to the bitbucket as I don't know which loggin/password to use): take it or leave it ! :D

On debian, I have a "real" cmake build (not the configure traces) in a dedicated BUILD directory (make things cleaner).
More important: getting find_package to work will be much more reliable than resorting to FindPETSc.cmake (often KO as architecture/OS specific...).

I would understand you give up with CMake for reason of your own reason (!)... 
But if so, the simple presence of CMakeLists.txt may be misleading (personal opinion: people can go "let's try to use it".).

Hope this helps !...

Franck
