Position Independent Code

CMake's standard CMAKE_POSITION_INDEPENDENT_CODE setting controls PIC for this project. You normally do not need to set it for shared builds, because CMake handles the shared library requirements.

Set it when building a static library that will later be linked into another shared library:

cmake -S . -B build -DBUILD_SHARED_LIBS=OFF -DCMAKE_POSITION_INDEPENDENT_CODE=ON

PIE flags for executables should be configured on the executable target that links to libsodium, not on the libsodium library target.

Autotools Compatibility Notes

Unlike upstream's Autotools build, this CMake build does not currently undefine NDEBUG; release builds may therefore compile out assert() calls unless that is handled separately.
