_I installed jsbsim git clone https://github.com/JSBSim-Team/jsbsim.git and build successfully then I installed PX4 packages git clone https://github.com/PX4/PX4-Autopilot.git and then make px4_sitl has no error but when I run make px4_sitl jsbsim for the jsbsim bridge with PX4 then the error came_

When I check the CMakeError.log It is shown as

Source file was:

include

I tried to remove and reinstall and also install repeatable but still getting same error

sudo apt-get remove/install libboost-all-dev

May I know the solution if anyone has the experience with this error?
