[freetype2] master 9224f05: [cmake] Honor SKIP_INSTALL_* settings (as used in zlib).

[Werner LEMBERG]

branch: master
commit 9224f05393485b44ca533015d37072d1ef2b3540
Author: David Capello <address@hidden>
Commit: Werner Lemberg <address@hidden>

    [cmake] Honor SKIP_INSTALL_* settings (as used in zlib).
    
    As FreeType depends on zlib, if we don't install zlib (e.g., because
    we defined SKIP_INSTALL_ALL), FreeType cannot be installed, too
    (cmake triggers an error saying that FreeType cannot be installed
    because zlib target isn't in the export set).
    
    * CMakeLists.txt: Honor `SKIP_INSTALL_HEADERS',
    `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL' settings.
