That dashboard build uses "bootstrap" so CMake is built with itself.
Therefore the new build flags appear during CMake's own build which
includes the test module in KWSys. That is the only shared library
built as part of CMake, so only that shows the warning.
The problem is in
Modules/Platform/CYGWIN-GNU.cmake
Modules/Platform/Windows-GNU.cmake
which currently have
set(CMAKE_SHARED_LIBRARY_${lang}_FLAGS "") # No -fPIC on cygwin
and
set(CMAKE_SHARED_LIBRARY_${lang}_FLAGS "") # No -fPIC on Windows
to override the Modules/Compiler/GNU.cmake settings.
They should be updated to override the PIC/PIE compile
option variables too.
