Review request for KDE Software on Mac OS X and KDevelop.


Changes
-------

addresses most issues.


Repository: kdevelop


Description
-------

This is a draft implementation for parser support of the `-iframework dir` and `-F dir` compiler arguments. On OS X these are the framework equivalents of `-isystem` and `-I` respectively, telling the compiler and/or linker where to find framework bundles.

I started out making the new code available on OS X only but that introduces a lot of #ifdefs for probably little benefit. On the contrary, clang supports the arguments on Linux too, presumably because clang is a functional cross-compiler that can generate Darwin Mach-O object files on Linux too.

For the 1st approach I propose to parse the framework directories, adding the effective header directories of the individual frameworks as if they were added explicitly. The framework directories are also added to a new list in the result structure. I presume that this is a prerequisite for adding them to the (lib)clang arguments of the clang parser.

Testing
-------

the unittest works as expected on OS X.

20160625: the patch works as expected on OS X. The `-iframework /opt/local/libexec/qt5/Library/Frameworks` argument added by cmake to each compiler invocation is detected and put to use; Qt header files are found in the frameworks without a wrapper Qt5 header directory (`/opt/local/include/qt5`) added to the header search path. Header files from the system SDKs are found too
