Configure 正在为IOS构建mobileVLCKit并获取错误，未找到软件包freetype2

但我确实安装了freetypes，它比要求的版本更高 值PKG_CONFIG_PATH包含freetype.pc文件

./compileAndBuildVLCKit.sh -f -b -v
...
checking for library containing iconv_open... 
-liconv checking for fabs in -lm... yes
checking pkg-config is at least version 0.9.0... yes
checking for FREETYPE... no
configure: error: Package requirements (freetype2 >= 9.10.3) 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.
make: *** [.ass] Error 1
ERROR: Building contribs failed

任何建议。关于如何解决这个问题

% echo $PKG_CONFIG_PATH
/usr/local/lib/pkgconfig

% find /usr/local -name "freetype*.pc"
/usr/local/lib/pkgconfig/freetype2.pc

% pkg-config --modversion freetype2
