* Makefiles: Normalize compiler-generated depfile pathsMarc Chevrier2021-07-021-3/+5
| | | | | | | | | | | | Even though Makefile generators pass source files and include directories by absolute path to the compiler, the compiler may generate depfile paths relative to the current working directory. For example, `ccache` with `CCACHE_BASEDIR` may transform paths this way. When reading a depfile, convert relative dependencies to absolute paths before placing them in `compiler_depend.make`, which is later evaluated in the top-level build directory. Fixes: #22364

* cmGccDepfileReader: Add new function ensuring paths are validMarc Chevrier2020-12-231-0/+34

* Add a parser for GCC-style depfilesJoerg Bornemann2020-01-281-0/+18
Introduce the function cmReadGccDepfile that parses a GCC-style depfile and returns its content. The implementation uses a lexer that is modeled after the re2c implementation in Ninja. The sample files of the autotest have been created with gcc 8.3.0. This depfile reader is to be used by the Autogen facility to make use of the depfiles that are generated by Qt's meta object compiler.
