Install FreeType2 by running the following commands: 

sed -ri "s:.*(AUX_MODULES.*valid):\1:" modules.cfg &&

sed -r "s:.*(#.*SUBPIXEL_RENDERING) .*:\1:" \
    -i include/freetype/config/ftoption.h  &&

./configure --prefix=/usr --enable-freetype-config --disable-static &&
make

This package does not come with a test suite.

Now, as the root user: 

make install

If you downloaded the optional documentation, install it as the root user: 

install -v -m755 -d /usr/share/doc/freetype-2.11.1 &&
cp -v -R docs/*     /usr/share/doc/freetype-2.11.1 &&
rm -v /usr/share/doc/freetype-2.11.1/freetype-config.1

Command Explanations

sed -ri ...: First command enables GX/AAT and OpenType table validation and second command enables Subpixel Rendering. Note that Subpixel Rendering may have patent issues. Be sure to read the 'Other patent issues' part of http://www.freetype.org/patents.html before enabling this option.

--enable-freetype-config: This switch ensure that the man page for freetype-config is installed.

--without-harfbuzz: If harfbuzz is installed prior to freetype without freetype support, use this switch to avoid a build failure.

--disable-static: This switch prevents installation of static versions of the libraries.
