Description dE 2018-07-01 13:12:17 UTC 
When cross compiling (using ROOT=), the build time dependencies are installed on the host (with the host's CFLAGS), and if the build time dependency is a static library, it's also copied from the host.

Setting SYSROOT, --sysroot, --root-deps does not make a difference. They just install the dependency in the ROOT but do not use it.

That really depends on the build system of the package in question, not portage.
Comment 2 Mike Gilbert gentoo-dev 2018-07-01 13:27:52 UTC 
Also, your cross-compiler (gcc, clang, etc) should be configured to look for libraries in SYSROOT instead of /. A tool like crossdev will set that up for you.
Comment 3 dE 2018-07-01 15:45:43 UTC 
So, this will not be possible with plane ROOT?
Comment 4 dE 2018-07-01 15:46:49 UTC 
Is there any documentation on how it can be achieved manually?
Comment 5 dE 2021-07-21 04:00:51 UTC 
Looks like I had hit this issue twice.
