Fix build submodules in non-camera-master compilation
This patch fixes two issues in non-camera-master (build-submodules) compilation:
- CMake installation directories
- Espia dependency in Frelon/Maxipix
The actual fix in the camera submodules is to set SIP_INCLUDE_DIRS
before calling limatools_run_sip_for_camera
in the same way that we set IMPORTS
