Description

With current trunk I get the following error message:

[ 77%] Building CXX object lib/CMakeFiles/dunegrid.dir/__/dune/grid/io/file/dgfparser/blocks/projection.cc.o

Same happened with UG and ALBERTA instead of ALUGrid.

I assume this was introduced by commit core/dune-common@75e2716b. Adding -DBUILD_SHARED_LIBS:BOOL=OFF to my CMAKE_FLAGS fixes the issue as it is like reverting the mentioned commit.
