LibSigMF compile fails only for SDRangel

[srs4511351]

Using a Raspberry Pi 5 The LibSigMF installation fails when I compile it with the SDRangel plugin procedure on Ubuntu 24.04 LTS The same procedure works with Raspberry Pi OS. I suspect that the newer packages used in Ubuntu 24.04 are the problem.

cd ~/SDRangel
git clone https://github.com/f4exb/libsigmf.git
cd libsigmf
git checkout "new-namespaces"
mkdir build; cd build
cmake -Wno-dev -DCMAKE_INSTALL_PREFIX=/opt/install/libsigmf .. 
make -j $(nproc) install

The failure occurs during the compiling of flatbuffers. I can successfully compile flatbuffers with a procedure similar to the one on https://github.com/google/flatbuffers. I don't know what is different in the SDRangel procedure.

cd /home/pi/SDRangel/libsigmf/external
git clone https://github.com/google/flatbuffers.git
cd flatbuffers
cmake -DCMAKE_INSTALL_PREFIX=/home/pi/SDRangel/libsigmf/build/flatbuffers-build .
make -j4
make install

I have attached the terminal output for the SDRangel LibSigMF compile.

I also installed the libsigmf/noble,now 1.0.2-2 arm64 package which installed the flatbuffers packages, but SDRangel did not find it even after I removed -DLIBSIGMF_DIR=/opt/install/libsigmf from the SDRangel cmake statement.
