[Integration] Struggling to build the example

[rbrigden]

Describe the bug Really appreciate this project! So far I've build and run the tests, and those work great. Currently struggling to build the example simulator outside of the stonefish repo assuming that I've install stonefish to my system with sudo make install.

To Reproduce

My setup:

/MyWorkspace/
  /example
    /main.cpp
    /MySimulationManager.cc
    /MySimulationManager.h
 CMakeLists.txt

#  CMakeLists.txt
add_executable(demo demo/main.cpp demo/MySimulationManager.cpp)

My steps:

cd MyRepo/demo
mkdir build
cd build
cmake ..
make

Output:

In file included from /MyWorkspace/demo/main.cpp:1:
/usr/local/include/Stonefish/core/GraphicalSimulationApp.h:29:10: fatal error: graphics/OpenGLDataStructs.h: No such file or directory
   29 | #include "graphics/OpenGLDataStructs.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make[2]: *** [CMakeFiles/demo.dir/build.make:76: CMakeFiles/demo.dir/demo/main.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/demo.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

Expected behavior

I expect this to build successfully and the system includes seem to work fine, but the relative includes fail to resolve. If I add an include_target_directories, I get linking errors.
