Compiler errors Glib无法找到libffi（即使使用cflags/pkgconfig！）

很抱歉，如果这是一个愚蠢的问题，但当我试图编译Glib时，它找不到libffi。我有静态库和共享库、pkgconfig文件、makefile中设置的cflags/libs，但它就是找不到

Makefile在LIBFFI_LIBS/CFLAGS中看起来像这样

LIBFFI_CFLAGS="-I/home/user/usr/i686-mingw32/lib/libffi-3.2.1/include -I/home/user/usr/i686-mingw32/include"
LIBFFI_LIBS="-L/home/user/usr/i686-mingw32/lib -lffi"

PKG_配置也已设置，在Konsole中运行时返回以下内容：

$ i686-w64-mingw32-pkg-config --libs --cflags libffi
-lffi
$

尝试

make V=1
