[cmake-developers] PIE for executables

[Craig Scott]

There was recent(ish) work to resolve an issue with ensuring executables
are built with PIE enabled for Android, but it would appear that for other
platforms, CMake might not be providing the required set of linker flags,
missing out on -pie. The end result is that despite having
POSITION_INDEPENDENT_CODE set to ON, executables might still be getting
built with PIE not enabled.

Those who are familiar enough with the various compiler/linker/platform
details may want to take a look at the following issue which ties together
the information from a few related bug reports:
