+## OpenFOAM® ThirdParty Environment Variables
+
+When using these scripts for building third-party libraries
+various environment variables are required or expected.
+
+### Mandatory
+
+- **WM_THIRD_PARTY_DIR** : Location of third-party library sources etc
+- **WM_PROJECT_DIR** : The OpenFOAM project directory. <br>
+  Used for `wmake` information, config files, etc
+- **WM_ARCH** : The target architecture (eg, Linux64)
+- **WM_OSTYPE** : The operating system type (eg, POSIX, MSwindows) <br>
+  Used as fallback for determining the ending for dynamic libraries.
+  Used for Windows-specific handling in scotch builds.
+- **WM_COMPILER** : The compiler name (eg, Gcc, Clang)
+- **WM_COMPILER_LIB_ARCH** : The target library ending (eg, 64). <br>
+  Typically used as `lib$WM_COMPILER_LIB_ARCH` to generate the name
+  `lib64`, for example.
+- **WM_LABEL_SIZE** : The OpenFOAM size for `label` (eg, 32 for int32)
+- **WM_PRECISION_OPTION** : The OpenFOAM representation for `scalar`
+  (eg, DP for double-precision)
+- **FOAM_EXT_LIBBIN** : Common _pool_ for the library targets.
+
+
+### MPI-related
+
+- **FOAM_MPI** : The OpenFOAM MPI sub-directory name (eg, sys-openmpi)
+- **WM_MPLIB** : The canonical OpenFOAM MPI name (eg, SYSTEMOPENMPI)
+- **MPI_ARCH_PATH** : Location of the current MPI implementation.
+  Used for additional linkage, but primarily to set MPI_ROOT
+  for a cmake hint.
+
+
+### Other
+
+- **WM_CONTINUE_ON_ERROR** : Ignore build errors.
+  Mostly set internally from `wmake -k`.
+- **WM_NCOMPPROCS** : The number of build processes to launch.
+  Often set internally from `wmake -j`.
+- **WM_COMPILER_TYPE** : Used internally for a few build scripts.
+  Has values of `system` or `ThirdParty`.
+
+
+## Output
+
+Similar to OpenFOAM itself, the build and final output are separated
+into different directories that contain a non-colliding hierarchy of
+target names. However, in contrast to the OpenFOAM target names,
+there are several different types of output targets:
+
+- *ARCH* : (eg, `linux64`) <br>
+  Base infrastructure such as compiler and base libraries.
+- *ARCH+COMPILER* : (eg, `linux64Gcc`) <br>
+  Compiler-specific libraries and applications.
+- *ARCH+COMPILER+SIZING* : (eg, `linux64GccDPInt32`) <br>
+  Libraries and applications specific to a particular combination
+  of OpenFOAM scalar/label sizes. This is the same as the
+  ***WM_OPTIONS*** value.
+
+By default, the locations of the build and final targets are hard-coded
+relative to the WM_THIRD_PARTY_DIR:
+
+- WM_THIRD_PARTY_DIR<b>/build/</b> : intermediate build artifacts
+- WM_THIRD_PARTY_DIR<b>/platforms/</b> : installation root
+
+The expert user or sys-admin can influence these locations with the
+following environment variables
+
+- **FOAM_THIRD_PARTY_BUILDROOT** :
+  Replaces WM_THIRD_PARTY_DIR as the root for build/ and platforms/.<br>
+  ***!! The specified build-root directory must exist !!***
+
+- **FOAM_THIRD_PARTY_SOURCES** :
+  Provide alternative location to WM_THIRD_PARTY_DIR/sources
+  for finding source bundles.<br>

+variables. For example,
+```
+CC="$(wmake -show-c)" CFLAGS="$(wmake -show-cflags)" ./configure
+```
+

+| | `wmake -show-cxxflags-arch` | Architecture information when linking |

+
+In some situations it can also be useful to have the compiler and flags

+## OpenFOAM® ThirdParty System Requirements
+
+For building some particular third-party libraries from source,
+the normal [OpenFOAM System Requirements][link openfoam-require]
+may not be sufficient.
+
+This is most notably the case for ParaView and/or QT compilation.
+As duly noted in [BUILD][link third-build] and [README][link third-readme] information,
+building ParaView from source tends to be the most difficult part of
+any third-party compilation.
+
+For general functionality, the paraview version distributed with
+the operating system or a [binary package][download ParaView]
+is likely [fully adequate for your needs][FAQ ParaView].
+
+
+***Please help us with keeping the information here up-to-date and accurate.***
+
+### Ubuntu
+
+The full dependency list for building ParaView can be found from the
+corresponding [debian/control][debian control] file.
+
+A ***quick*** way to get these dependencies on to your system is to
+use the paraview development package:
+```
+sudo apt install paraview-dev
+```
+Depending on your setup, the following subset may also be enough:
+```
+sudo apt install cmake qtbase5-dev qttools5-dev qttools5-dev-tools libqt5opengl5-dev libqt5x11extras5-dev libxt-dev
+```
+
+
+### openSUSE (eg, Leap-15.3)
+
+The full dependency list for building ParaView can be found from the
+corresponding [rpm spec][suse spec] file.
+
+A ***quick*** way to get these dependencies on to your system is to
+use the paraview development package:
+```
+sudo zypper install paraview-devel
+```
+
+Depending on your setup, the following subset may also be enough:
+```
+sudo zypper install Mesa-libEGL-devel
+sudo zypper install libqt5-qtbase-devel libqt5-qtsvg-devel libqt5-qttools-devel libqt5-qtx11extras-devel
+sudo zypper install libxcb-devel libXt-devel
+```
+
+For building paraview with ffmpeg support (components: avformat
+avcodec avutil swscale), the packman repository may be required, with a
+variety of additional packages:
+```
+sudo zypper install ffmpeg-3
+sudo zypper install ffmpeg-3-libavcodec-devel
+sudo zypper install ffmpeg-3-libavformat-devel
+sudo zypper install ffmpeg-3-libavresample-devel
+sudo zypper install ffmpeg-3-libavutil-devel
+sudo zypper install ffmpeg-3-libswresample-devel
+sudo zypper install ffmpeg-3-libswscale-devel
