[CMake] Include directory issue ... -I are not separated?

[Ateljevich, Eli]

Eric
I have improved my envvar usage a bit further, I hope, by saying 
include_directories( $ENV{NETCDF_INC} ) 
rather than 
include_directories( ${NETCDF_INC} )

However, I am now quite sure that what is happening is when I put hardwired absolute paths in include_directories it is used as-is, but when I put in environment variables the project build path is being prepended to it. Can I disable this?

Thanks,
Eli

I appreciate your patience as I seem to be struggling reporting some of the details properly. The real invocation is and has always been this:
cmake -DCMAKE_Fortran_COMPILER=mpif90 ../src

The CMakeLists.txt is below verbatim.
1. If I change to curly braces I get no -I in the compile command at all and the environment variable evaluates empty. 
2. If I go back to parentheses I get the "double -I" problem as before.
3. If I ditch environement variables entirely the file compiles and I am on to the next error: 
include_directories (. /usr/local/dms/pkg/netcdf/4.1.3-intel12.0-parallel/include)

Interestingly, if I don't include the "." the next error has to do with not having the local build directory (src/Hydro) on the include path. So I guess I really do want both parts of the -I, I just don't want them glommed together.

Thanks again,
Eli

> Addendum: I should add that by now I have taken the failure line, put a space in between the two -I components and run it directly in the shell and verified it compiles fine (and without the space it fails as in cmake).

Yes right. Collating -I shall fail, no problem.
The question is why your CMakeLists.txt is generating such command line?

As always evil may be in the details.
Would you be able to copy/attach your CMakeLists.txt "verbatim"?

Your previous quote shall not work since
$(NETCDF_INC) is not a proper CMake syntax
CMake uses braces i.e. ${NETCDF_INC} and not parenthesis.

cmake -DCMAKE_Fortran_COMPILER ../src

is wrong as well (no compiler value defined)
and is probably not the good way to chose the Fortran compiler.

Please give us "exact" content (which may be an excerpt) of your
CMakeLists.txt and command lines used.
