Hi,

Today I tried to install dolfin 1.4 in Fedora 20. I've worked with dolfin
1.3 until now.

Using the following commands

cd <fenics directory>
mkdir buildcd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/fenics-1.4.0 ..

I've got errors in

-- The following optional packages were found:--
--------------------------------------------- (OK) OPENMP-- (OK) MPI--
(OK) PETSC-- (OK) UMFPACK-- (OK) CHOLMOD-- (OK) CGAL-- (OK) ZLIB--
(OK) PYTHON-- (OK) SPHINX-- (OK) VTK-- (OK) QT-- -- The following
optional packages were not found:--
------------------------------------------------- (**) PETSC4PY-- (**)
SLEPC-- (**) TRILINOS-- (**) PASTIX-- (**) SCOTCH-- (**) PARMETIS--
(**) HDF5

"/home/mrosa/Downloads/fenics-1.4.0/dolfin-1.4.0/build/CMakeFiles/CMakeOutput.log".See
also 
"/home/mrosa/Downloads/fenics-1.4.0/dolfin-1.4.0/build/CMakeFiles/CMakeError.log".

I read and read this files from cmake but I could not find what was wrong
since I installed fenics 1.3 using the same linux commands with the same
system libraries.

So I decided to manually turn off the optional packages cmake could not
find (since I did not installed them).

After that, everything was fine.

So I think your could put a note in cmake files or in a readme file saying
that we must turn off packages we did not have, or cmake will display
errors.

Well hope this note helps someone with similar difficulties.

Regards, Marcelo
