about Android Tablet "can0"

[jnghhk]

hello!
I've been using can-utils on my ubuntu-based pc for a while.
I'm trying to use a USB CAN device on my Galaxy tab S7 this time.
It's my first Android, so I'm asking a question because it's difficult to access.
The tablet is rooted, and android studio is installed on the PC.
I installed termux on the tablet and acquired "sudo" , but it seems that additional work is required to use the command "$ sudo ip link set can0 up type can bitrate 500000" that I have been using.
If you look at the CMake Project Generator part, there is a method in Android and Android Studio, but I did not understand.
The way I did it was to download can-utils using termux,
$ mkdir build
$ cd build
$ cmake -DCMAKE_TOOLCHAIN_FILE=~/Android/Sdk/ndk-bundle/build/cmake/android.toolchain.cmake -DANDROID_PLATFORM=android-21 -DANDROID_ABI=armeabi-v7a .. && make
I did the above, but it seems to have failed because there is no toolchain.
Where is DCMAKE_TOOLCHAIN_FILE?
I'm not good at English, but thank you for reading.
