如遇报错：
checking for FREETYPE... configure: error: Package requirements (freetype2) were not met:
No package 'freetype2' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables FREETYPE_CFLAGS
and FREETYPE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
加上环境路径再试：export PKG_CONFIG_PATH=/usr/local/freetype/lib/pkgconfig
