Summary	0004575: SlicerConfig unsets CMAKE_CXX_FLAGS
Description	The following line ends up setting `CMAKE_*_FLAGS` to the empty string in several projects I've checked (mac and windows): https://github.com/Slicer/Slicer/blob/master/CMake/SlicerConfig.cmake.in#L462 If I'm following correctly, the `"@Slicer_CMAKE_CXX_FLAGS_CONFIG@"` substitution variable there is supposed to be set at the following line: https://github.com/Slicer/Slicer/blob/master/CMake/SlicerGenerateSlicerConfig.cmake#L25 But it looks like `ep_common_cxx_flags` only exists at the SuperBuild level now (?), not at the application project level (Slicer-build directory). This means that `find_package(Slicer ...)` will unset an existing variable, before even including the Use file.
