Hi everyone,
<div><br>
</div>
<div>We use CMake to create the build files for our C++ research code. We compile all source files directly into one executable and then link statically to a couple of external libraries.</div>
<div><br>
</div>
<div>However, I noticed that CMake adds the '-fPIE' flag to the compilation flags without me asking for it. When I set up a simple dummy C++ CMake project, no '-fPIE' was added to the compilation flags. Do you know what could cause this flag to be added? As
far as I know, the -fPIE/-fPIC flags require one additional register to be used for the code locations, thus rendering the code slightly less efficient.</div>
<div><br>
</div>
<div>Regards,</div>
<div><br>
