Summary0015684: CMAKE_Fortran_COMPILER_VERSION becomes unset after second configuring
DescriptionCMAKE_Fortran_COMPILER_VERSION contains the correct version after the first configuring (first run of cmake), but becomes undefined after the second configuring. Is this normal behavior?
Steps To ReproduceTry, e.g.,

  message("test 1 " ${CMAKE_C_COMPILER_VERSION})
  message("test 2 " ${CMAKE_Fortran_COMPILER_VERSION})

The first time it prints

  test 1 5.2.0
  test 2 5.2.0

in my system, but after the second run of cmake it prints

  test 1 5.2.0
  test 2

I can reproduce this behavior for the Makefile Generator on RHEL6:
- with gcc and gfortran 4.8.1
- with icc and ifort 15.0.3

A possible workaround is to add a set command immediately after the project command:

project( myCF90project Fortran C )
set( CMAKE_Fortran_COMPILER_VERSION ${CMAKE_Fortran_COMPILER_VERSION} CACHE STRING "Fortran compiler version string" FORCE )

Fixed:

 Fortran: Store detected compiler version persistently

I've queued this for merge to the 'release' branch for inclusion in 3.3.1.
