@ABee81 We currently only support -isystem and not |

@sean-mcmanus Thanks for you quick answer! I also never saw it before, but In QNX SDP Documentation I could find some additional information: the -Wp argument of qcc passes the following arguments to the preprocessor. If its possible it would be great to have this as a feature, up to then we will be using a script to replace -Wp,-isystem with just -isystem |

@sean-mcmanus after more deeper analysis into the issue I think it is not a cpptools issue. I have opened an issue for CMake (https://gitlab.kitware.com/cmake/cmake/-/issues/26912). Depending on response of Kitware/CMake, this feature might not be needed |

Bug Summary and Steps to Reproduce
Bug Summary:
For the following Test_Workspace:
Test_Workspace/
After executing the build, CMake generates compile_commands.json file inside build/qnx710 folder. When adding compile_commands.json path to the c_cpp_properties.json configuration of the workspace, the system includes in with the format "-Wp,-isystem,/home//Test_Workspace/inc" are ignored/not parsed correctly by cpptools. Navigating to the header files in the system include folder is not working, error squiggles and the message:
#include errors detected. Consider updating your compile_commands.json or includePath. Squiggles are disabled for this translation unit (/home/Test_Workspace/main.c).C/C++(1696)
Steps to reproduce:
Expected behavior:
cpptools parsed sytem include path correctly and navigating to the header files in the system include path works without errors. No error squiggles should be shown.
