[Dune-devel] [Dune-Commit] [Commit] dune-common - dde56b3: [CMake] Get rid of warnings related to CMP0019: skip include/link variable re-expansion

[Christoph Grüninger]

Hi Markus,
I tested it with ctest in dune-geometry in the default build directory 
build-cmake and it worked. The same for a dumux test. Is it now broken 
for you?

I would like to fix this issue and not fumble around with the policy 
setting. Sure we can set CMP0019 to the old behavior but that will shift 
our problem to the future.

According to [1] its not possible to define a version and set all future 
policies to old:
"cmake_policy(VERSION major.minor[.patch[.tweak]])

Specify that the current CMake list file is written for the given 
version of CMake. All policies introduced in the specified version or 
earlier will be set to use NEW behavior. All policies introduced after 
the specified version will be unset (unless variable 
CMAKE_POLICY_DEFAULT_CMP<NNNN> sets a default). This effectively 
requests behavior preferred as of a given CMake version and tells newer 
CMake versions to warn about their new policies."

Bye
Christoph
