Subject: [PATCH] cmake: enable position independent code (PIE)

Fixes the following build error when compiling Fedora 45 RPM:

/usr/bin/ld.bfd: tests/unit/CMakeFiles/tests.dir/tests.cpp.o: relocation R_X86_64_32 against `.rodata' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld.bfd: failed to set dynamic section sizes: bad value
collect2: error: ld returned 1 exit status

See: https://cmake.org/cmake/help/latest/prop_tgt/POSITION_INDEPENDENT_CODE.html
