I'm trying to buld Krita for Android on Ubuntu 22.04 for 2 days already but I'm always getting this ECM required error.

ECM version 5.92 is installed (of course) under /usr/share/ (via apt-get install extra-modules-cmake).

Here's the error output:

[ 33%] Built target ext_extra_cmake_modules
[ 33%] Performing configure step for 'ext_kconfig'
-- Could NOT find ECM (missing: ECM_DIR)
--
* ECM (required version >= 5.64.0), Extra CMake Modules., <https://projects.kde.org/projects/kdesupport/extra-cmake-modules>

CMake Error at /usr/share/cmake-3.22/Modules/FeatureSummary.cmake:464 (message):
feature_summary() Error: REQUIRED package(s) are missing, aborting CMake
run.


Building for Desktop-Linux works fine.
I tried all kinds of things, like specifing the ECM dir via the -D flag or exporting it as an environment variable but no luck so far.
I also wonder why it builds fine when building for Linux.

The full build output is below.
Since other people also had issues with CMake and found help here, does anybody here have experience with building for Android?
