Can't compile pdlib

[edgeofthex]

Hello,

I'm running debian bullseye. Following the instructions in the wiki, I was able to compile dlib, but pdlib won't compile. I'm trying to compile with g++ version 10.2.1.1 . When I first ran make I got the following message:

"Dlib requires C++14 support. Give your compiler the -std=c++14 option to enable it."

I added the option to configure thusly: ./configure --enable-debug CFLAGS=-std=c++14

the present error I'm getting follows:

make

I think I just need to add that compiler flag correctly. Can anyone help? Thanks!
