# freetype_nohb/CMakeLists.txt

# Configure the build of freetype_nohb.

# To follow what is recommended by BLFS, the freetype package (which
# is identical to the current package except for the --with-harfbuzz
# configure option) depends on harfbuzz, which in turn depends on the
# current package which because it uses the --without-harfbuzz
# configure option depends on no other package.

# Note BLFS recommends the extra steps of installing the
# documentation, enabling GX/AAT and OpenType table validation, and
# enabling Subpixel Rendering and Subpixel Hinting in order to improve
# font rendering.  However, for simplicity we do none of those extra
# steps for now (which also renders moot the possibility [discussed in
# detail by BLFS] that Subpixel Rendering _might_ be patent
# encumbered).
