Summary

0015491: First-class support for GNU -iquote, -I- and -I=opt/foo include directory specifiers

Description

The -iquote and -I- options relate to how the compiler treats "" versus <> includes.

https://gcc.gnu.org/onlinedocs/cpp/Search-Path.html [^]

All -iquote options are processed before any -I options. A new target property and directory property and command interface could be added for it.

The -I- is a divider. CMake could support it by accepting a placeholder of a magic name in the INCLUDE_DIRECTORIES property. This would need to be allowed only in non-transitive uses.

https://gcc.gnu.org/onlinedocs/cpp/Invocation.html#Invocation [^]

"If dir begins with =, then the = will be replaced by the sysroot prefix; see --sysroot and -isysroot."

It is possible that CMake could learn to use that. I'm not certain whether that would be useful though, as I think CMake already adds the sysroot as a prefix during generation.

I have not checked other compilers for equivalent features.
