failed to parse dependencies from Fortran sources

with CMake version: 3.10.2 we are getting these warnings, and we have no cluse why Fortran parsing failed:

warning: failed to parse dependencies from Fortran source '/builds/dirac/dirac/src/krcc/krcc_inp.F': syntax error, unexpected WORD

Failed parsing is causing compilation errors. Our software project contains mix of Fortran sources - Fortran77,Fortran90.

At least we would welcome more informative printout why the parsing failed.

With lower CMake versions we do not observe parsing failures.
