Error when compiling for ARM

[marco-trovato]

I tried to build in aarch64 inside Termux (Android) and everything went smooth until the linking process, i got a "libiconv" error message (but libiconv is installed).
Make output:

I apologize inadvance if it is a noob question, but I really don't understand what I'm doing wrong: it compiled without any problem on Debian_x86_64, and I can't find any further info about this error anywhere online.

configure with
LDFLAGS=-liconv cmake ...

Thank you for your help. I tried but nothing has changed, am I missing something?
I am only interested in the curses/terminal version, and I have set to "false" all the QT, GTK2, and GTK3 flags.

you need to configure with LDFLAGS

LDFLAGS=-liconv cmake -S . -B build_dir -D CMAKE_BUILD_TYPE=RelWithDebInfo \
	-D CMAKE_INSTALL_PREFIX=build_dir/install
cmake --build build_dir -j # compiled binaries are in build_dir/
cmake --install build_dir # self-contained installation is in build_dir/install/

You are a saviour! It worked!
THANK YOU!!!

I hope this will help other people that will get the same error when trying to use this awesome editor on their ARM devices
