=============================DEBUG ASSISTANCE=============================
If you are seeing a compilation error please try the following steps to
successfully install cmake:
1) Upgrade to the latest pip and try again. This will fix errors for most
users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
2) If running on Raspberry Pi OS, you can set PIP_ONLY_BINARY=cmake in
order to retrieve the latest wheels built by piwheels.
c.f. https://github.com/scikit-build/cmake-python-distributions/issues/392#issuecomment-1676284749
3) If on Linux, with glibc < 2.12, you can set PIP_ONLY_BINARY=cmake in
order to retrieve the last manylinux1 compatible wheel.
4) If on Linux, with glibc < 2.12, you can cap "cmake<3.23" in your
requirements in order to retrieve the last manylinux1 compatible wheel.
5) Open an issue with the debug information that follows at

We are currently working on packaging improvements using a different approach, not relying on Kivy anymore. It will be available in a few weeks. I know it hurts, but thank you for your patience.
For curious this is the list of Python packages I'm trying to assemble from various frameworks, to understand what should be supported in Flet first of all: https://docs.google.com/spreadsheets/d/1bZwiWyxWzReJmSd6iOlZVRNWLa9oYV0ci49coRJzZss/edit?usp=sharing
I'm going to create a voting section on the forums to collect everyone's feedback.
Same problem, but I cant build when using firebase_admin
