When searching for frameworks, if the file is specified as ``A/b.h``, then
|
|
|
|
|
the framework search will look for ``A.framework/Headers/b.h``. If that
|
|
|
|
|
is found the path will be set to the path to the framework. CMake
|
|
|
|
|
will convert this to the correct ``-F`` option to include the file.
