Notes:

• If you use a Makefile and have generated a compile_commands.json file from it (see compile_commands.json), the include path fields in your compilation database may have been automatically populated. In this case, you shouldn't need to do anything more.
• The GCC version number (listed above as 7.2.1) may vary based on platform and toolchain version. You can find out what version you have by running arm-none-eabi-gcc --version and substitute the listed value for the version in the include path.
• /usr/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/include/c++/7.2.1/arm-none-eabi/thumb/v7-ar/fpv3/softfp may vary based on the architecture for which you are compiling.
• On Windows, the path /usr/bin/../ is the root directory of wherever you installed the toolchain (so it should have the folders arm-none-eabi, bin, lib, and share, as well as an uninstall executable).
• If you are unable to index files, check that cquery is not trying to build your files with Microsoft extensions (see cquery-project/cquery#509)
