min_cmake_preproc

Just two minimal examples for some issues I am having with Fortran in vscode.

highlighting_eg.fpp has a lot of red squiggles everywhere. If I rename it to highlighting_eg.fypp then those red squiggles go away. However, everything after the type definition loses syntax highlighting.

min_eg.F90 is builds two binaries from CMakeLists.txt, which defines NUMBER_PREPROCESSED to be either real or complex. I have defined it to be real for the purposes of vscode, in .vscode/settings. This gives an error (red squiggle) even though when you hover over it you correctly see #define NUMBER_PREPROCESSED real.

More annoyingly, if this is a module instead of a program, e.g.

module min_eg
    use iso_fortran_env, only: dp => real64
    implicit none
    contains
    subroutine print_stuff(some_number)
        NUMBER_PREPROCESSED(dp) :: some_number ! = 1.
        ! should be preprocessed to:
        ! real(dp) :: some_number ! = 1.
        print*, some_number
    end subroutine
end module min_eg

then the .mod file gets deleted. In the context of a bigger project, this then messes up intellisense in other files, as it thinks the module doesn't exist.
