Message : Another adjustment to header locations. This change is a result of a discussion thread on freetype-devel http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html Re-introduce the `freetype2' subdirectory for all FreeType header files after installation, and rename the `freetype2' subdirectory in the git repository to `freetype'. * include/freetype2: Renamed to... * include/freetype: This. * CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS, PRIVATE_HEADERS): Updated. Update creation of `ftconfig.h'. Install generated `ftconfig.h'. * Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated. * builds/amiga/include/config/ftconfig.h, builds/freetype.mk (PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work), builds/unix/freetype2.in: Updated. * builds/unix/freetype-config.in: Updated. * builds/unix/configure.raw: Don't check for `rmdir'. * builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable according to the autoconf info manual. * builds/unix/install.mk (install, uninstall, distclean_project_unix): Update and simplify. * builds/wince/*, builds/windows/*: Updated. * devel/ft2build.h, include/ft2build.h: Updated. * include/freetype2/config/ftheader.h, include/freetype2/internal/ftserv.h, include/freetype2/internal/internal.h: Update all header file macros. * src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated. * docs/*: Updated.
