They can be specified on the CMake command line (with the -D flag) or in the environment. + +KERNEL module: + +* LIBBATCH_ROOT_DIR: LibBatch package - already uses Python, Swig and PThread +* PYTHON_ROOT_DIR: Python package +* PTHREAD_ROOT_DIR: PThread package - typically not need on Unix systems +* SWIG_ROOT_DIR: SWIG package +* LIBXML2_ROOT_DIR: LibXml2 package +* HDF5_ROOT_DIR: HDF5 package - if HDF5 was compiled with MPI support, the corresponding MPI root directory will be exposed automatically (no need to set MPI_ROOT_DIR) +* BOOST_ROOT_DIR: Boost package +* OMNIORB_ROOT_DIR: OmniORB package +* OMNIORBPY_ROOT_DIR: OmniORB Python backend - if not given, OMNIORB_ROOT_DIR will be tried +* MPI_ROOT_DIR: MPI package (see HDF5_ROOT_DIR above) +* CPPUNIT_ROOT_DIR: CppUnit package +* DOXYGEN_ROOT_DIR: Doxygen package +* GRAPHVIZ_ROOT_DIR: Graphviz package +* SPHINX_ROOT_DIR: Sphinx package - requires setuptools and docutils to work properly. +* SETUPTOOLS_ROOT_DIR: Setuptools package. This package is not detected explicitly in the KERNEL, but the path is used to complete the PYTHON path given to Sphinx. +* DOCUTILS_ROOT_DIR: Docutils package. This package is not detected explicitly in the KERNEL, but the path is used to complete the PYTHON path given to Sphinx. + +GUI module - on top of some of the KERNEL prerequisites, the following variables are used: + +* VTK_ROOT_DIR: VTK package. If not given, PARAVIEW_ROOT_DIR is used to look for a VTK installation inside the ParaView installation +* (optional) PARAVIEW_ROOT_DIR: see above +* CAS_ROOT_DIR: Cascade package +* SIP_ROOT_DIR: SIP package +* QT4_ROOT_DIR: Qt4 package (only some components are loaded) +* PYQT4_ROOT_DIR: PyQt4 package +* QWT_ROOT_DIR: Qwt package +* OPENGL_ROOT_DIR: OpenGL package + +MED module - on top of some of the KERNEL and GUI prerequisites, the following variables are used: + +* MEDFILE_ROOT_DIR: MEDFile package +* METIS_ROOT_DIR (optional): Metis package +* PARMETIS_ROOT_DIR (optional): ParMetis package +* SCOTCH_ROOT_DIR (optional): Scotch package + +PARAVIS module - on top of some of the KERNEL, GUI and MED prerequisites, the following variables are used: + +* PARAVIEW_ROOT_DIR: ParaView package +* at present for a proper build of PARAVIS, the env variables LD_LIBRARY_PATH and PYTHONPATH should be set to contain the HDF5 and ParaView libraries.

The detection logic of CASCADE should make sure Tbb gets included. + +* Being able to use different versions/installations of the same product, in the system, or generated by the user. + For instance, using the system python 2.7, or a user-compiled python 2.6. +* The detection of prerequisites is driven by user options. + For example MPI is detected only if option SALOME_USE_MPI is ON. +* Detection of first order prerequisites is based on a _ROOT_DIR variable or on what has been detected in another dependency. For example if both HDF5 and MPI are needed by the current module, we try to detect with which MPI installation HDF5 was compiled, and to offer this one as a default choice for the package itself. Other variables (PATH, LD_LIBRARY_PATH, PYTHONPATH) should never be needed at compile time. +* The only exception to the previous point is Python, which is so central to the process that we assume that LD_LIBRARY_PATH and PYTHONPATH are already correctly pointing to the correct Python installation. +* Trying as much as possible to detect potential conflict, and warn the user: + + * if the package was detected at a place different from what was specified in XYZ_ROOT_DIR + * if there is a conflict between what was explicitly set in XYZ_ROOT_DIR, and what was previously used in a dependency + + +
