I often build with

but recently this has quit working because CMake fails to add the
necessary -fPIC flag to shared library builds.
Sorry I don't know the last CMake version where this worked, but I am
pretty
sure I have used this sort of build successfully for earlier versions of
2.8.x, and definitely for cmake-2.6.4.
If I specify the flags another way, e.g.,
cmake -DCMAKE_C_FLAGS:STRING="-g -fvisibility=hidden" \
-DCMAKE_CXX_FLAGS:STRING="-g -fvisibility=hidden" \
-DCMAKE_Fortran_FLAGS:STRING="-g -fvisibility=hidden" \
...
the necessary -fPIC flag for shared libraries is added in properly.
However,
I would like the more convenient (set and forget) environment variable
approach to continue to work as previously.
Perhaps adding the flags causes the compiler to be mis-identified
somehow. Can you run with the gcc -g -fvisibility=hidden, and without
on a very simple C only project. Then send me the binary trees from
both. I am suspecting there will be some sort of error in the compiler
id code.
