Autogen: Do not treat hard-coded -I/usr/include exclusion as implicit include (!3159) · Merge requests · CMake / CMake

Sebastian Holtermann requested to merge sebholt/cmake:include_directories_filter into master Mar 28, 2019

The cmLocalGenerator::GetIncludeDirectoriesImplicit method is called by cmQtAutoGenInitializer to get the compiler's list of implicit include directories. Since !2957 (merged) the method hard-codes exclusion of /usr/include for historical reasons. However, it should not be reported as a real implicit include directory unless the compiler really has it.

Refactor the logic to distinguish the hard-coded exclusion of /usr/include from the real list of implicit include directories.

Fixes: #19100 (closed)
