I want to add a custom shared library, I can compile it in yocto (using a separate computer) so it is in /usr/lib on the target But how would i add that to the leaf setup used for VSCode so i can compile against it in my app? Can i just copy the needed libraries and header files into /home/pm/.leaf/wp77-toolchain\_SWI9X06Y\_03.00.13.00-linux64/sysroots/armv7a-neon-poky-linux-gnueabi/ or would that break things ? ---
