Build from source on termux (aarch64)

[BufuWinner]

I've been trying to build from source in termux (Linux) with the aarch64 architecture (not in the releases).
Many dependencies can't be installed from the package manager, by I tried my best to get everything. After many tries though I still get this error ->

CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: LIBPANEL linked by target "musikcube" in directory /data/data/com.termux/files/home/musikcube/src/musikcube -- Generating done CMake Generate step failed. Build files cannot be regenerated correctly.

Does any one know which package sets the variable to something?
Sorry if it's a simple/stupid question but I can't go on with the installation...
Thanks in advance for any help!

musikcube has a number of dependencies that must be available on the system that are described here: https://github.com/clangen/musikcube/wiki/building -- unfortunately some of these may not be available in termux.
