Debian bullseye - can't find libraries (z3, grpc++) in stage 2

[sylvestre]

Recently, stage 2 on debian bullseye (amd64) is failing with:

-- flang project is disabled
CMake Warning at cmake/modules/FindZ3.cmake:116 (message):
  Failed to determine Z3 library version, defaulting to 0.0.0.
Call Stack (most recent call first):
  CMakeLists.txt:506 (find_package)


-- Could NOT find Z3: Found unsuitable version "0.0.0", but required is at least "4.7.1" (found Z3_LIBRARIES-NOTFOUND)
CMake Error at CMakeLists.txt:515 (message):
  LLVM_ENABLE_Z3_SOLVER cannot be enabled when Z3 is not available.

Enabling the debug -DCMAKE_FIND_DEBUG_MODE=ON
it is searching the libs in
/usr/lib/x86_64-pc-linux-gnu/
while the lib is in
/usr/lib/x86_64-linux-gnu/

de4364f was ok

de4364f was ok

Was de4364f the last known good revision? What's the first known bad revision? Can you bisect @sylvestre ?

I did and it is actually that these options on the packaging side have been removed during a merge...
my bad
