Hi

I am installing OFv2112 on RH8.3. I am Using the system compiler (gcc 8.5.0) and cmake (3.20.2). GMP, MPFR and MPC packages were also installed.

The bashrc file specified the system compiler be used.

Compilation generally went well (Allwmake), except issues were reported with CGAL as follows.

-offsetof -Wno-attributes -Wno-unknown-pragmas -O3 -DNoRepository -ftemplate-depth-100 -fPIC -O3 -DNDEBUG'
-- USING LDFLAGS = '-m64 '
-- Configuring incomplete, errors occurred!
See also "/fsx/apps/OpenFOAM/ThirdParty-v2112/build/linux64Gcc/CGAL-4.14.3/CMakeFiles/CMakeOutput.log".

    ---------------------------------------------------
    Optional component (CGAL) had build issues
    OpenFOAM will nonetheless remain largely functional
    ---------------------------------------------------

I could not see an obvious error in the referred log. There was an additional message:

Configuring libCGAL
CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find GMP (missing: GMP_LIBRARIES GMP_INCLUDE_DIR)
Call Stack (most recent call first):

  cmake/modules/CGAL_SetupGMP.cmake:24 (find_package)
  cmake/modules/CGAL_SetupCGALDependencies.cmake:41 (include)
  src/CGAL/CMakeLists.txt:5 (include)

I have tried downloading and manually extracting, configure, make, make install of the latest version of the gmp library, and manually setting and exporting the variables mentioned, but no change.

How can I configure OF to build CGAL correctly and refer to the GMP libraries installed?

The CGAL configure script appeared to only specify the GMP, MPC and MPFR version if the compiler variable is set to ThirdParty, mine is set to system.

Thank you for any comments and advice.
