[DFTB-Plus-User] compiling 22.2 - error in compiling MBD section

[Carlo Nervi]

Dear developers of dftb+ 22.2,
I'm compiling dftb+ version 22.2 (github version) under linux gentoo.
I switched on (in config.cmake) WITH_MPI, WITH_TBLITE, WITH_MBD and
WITH_SDFTD3

The compilation with cmake proceed up to the point concerning MBD.
It must be pointed out that with 22.1 I had no problems in compiling.
Now the following error appears:

[  6%] Built target test_gather
[  6%] Built target test_gatherv
[  8%] Built target scalapackfx
[  8%] Building Fortran object
