compilation problem - mpi.h not found

Hey guys!

Just set up a new Ubuntu 22.04 machine from scratch:

installed moose without any issues with the mamba generated env
installed qt (5.10.1)
set the libmesh-path in my meshit.pri to "/home/wuff/mambaforge/envs/moose/libmesh"

but when trying to compile I get a strange error linked to my MPI wrapper even though it looks fine to me:

(moose) wuff@wuff:~/projects/MeshIt$ which mpicc mpicxx mpif90
/home/wuff/mambaforge/envs/moose/bin/mpicc
/home/wuff/mambaforge/envs/moose/bin/mpicxx
/home/wuff/mambaforge/envs/moose/bin/mpif90

the error:

g++ -c -pipe -O2 -w -D_REENTRANT -fPIC -DTRILIBRARY -DEXTERNAL_TEST -DQT_NO_DEBUG -DQT_OPENGL_LIB -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I. -Iinclude -I. -I../../mambaforge/envs/moose/libmesh/include -I. -I../../mambaforge/envs/moose/libmesh/include/libmesh -I../../mambaforge/envs/moose/include/qt -I../../mambaforge/envs/moose/include/qt/QtOpenGL -I../../mambaforge/envs/moose/include/qt/QtWidgets -I../../mambaforge/envs/moose/include/qt/QtGui -I../../mambaforge/envs/moose/include/qt/QtCore -I. -I../../mambaforge/envs/moose/mkspecs/linux-g++ -o geometry.o src/geometry.cpp

any idea how to fix this?
