ERROR: freetype2 not found using pkg-config

[alicera]

Follow the installation and add --enable-libfreetype.
I use --extra-cflags and --extra-ldflags to assign the path of libfreetype binary.
But meet the error ERROR: freetype2 not found using pkg-config and it try to use pkg-config to find freetype2 .pc file

END ./ffconf.XlJKo3ZL/test.cu
nvcc -gencode arch=compute_52,code=sm_52 -O2 -m64 -ptx -c -o ffconf.XlJKo3ZL/test.o ffconf.XlJKo3ZL/test.cu

You have to create your own .pc file and use the dll version import library.
You can't use the static version of the library with MinGW or you will have to compile a static MinGW library yourself from the freetype sources.

1. How to create .pc ?
2. I use freetype-windows-binaries and build ffmpeg with --extra-cflags="-I../freetype-windows-binaries-2.11.1/include" and --extra-ldflags="-LIBPATH:../freetype-windows-binaries-2.11.1/win64"
   So, the method is mistake ?
