[CMake] ccmake and fortran

[bpwlist at cox.net]

Thanks Karl, that got me looking in the right direction:

Changing the line

<fixed_fmt>^[cC*dD].*\n { return EOSTMT; }

to:

^[cC*dD].*\n { return EOSTMT; }

in cmDependsFortranLexer.in.y fixes the problem.  This forces the parser to ignore comment lines.

I also discovered that include paths are not searched properly when the dependecies are written out .  I set my include paths in the CMakeLists.txt as follows:

INCLUDE_DIRECTORIES(
	include/
)

Included files under the "include/" directory are not written out to depend.make.  I have traced the problem part way down.  It appears that when cmLocalUnixMakefileGenerator3.cxx constructs the cmFortranDepends object that the includes path vector is empty.  The code loops through each language, the paths gets set for C++ but not for Fortran.  The code is looking for the CMAKE_Fortran_INCLUDES to contain the paths, but the variable is empty.   Anybody have any ideas for a quick fix?

Thanks,

Bryan Walsh
