Unable to link with libx264.lib static library

Question

I'm building custom video encoder using x264 as a static library. I've followed this guide in order to build static library. Trying to compile this:

x264_t * setup_encoder(int width, int height){
    x264_param_t param;
    x264_param_default_preset(&param, "veryfast", "zerolatency");
    param.i_threads = 1;
    param.i_width = width;
    param.i_height = height;
    param.i_fps_num = 26;
    param.i_fps_den = 1;
    // Intra refres:
    param.i_keyint_max = 26;
    param.b_intra_refresh = 1;
    //Rate control:
    param.rc.i_rc_method = X264_RC_CRF;
    param.rc.f_rf_constant = 25;
    param.rc.f_rf_constant = 25;
    param.rc.f_rf_constant_max = 35;
    //For streaming:
    param.b_repeat_headers = 1;
    param.b_annexb = 1;
    x264_param_apply_profile(&param, "baseline");

    return x264_encoder_open(&param);
}

Results in:

main.obj : error LNK2019: unresolved external symbol "int __cdecl x264_param_default_preset(struct x264_param_t *,char const *,char const *)"

main.obj : error LNK2019: unresolved external symbol "int __cdecl x264_param_apply_profile(struct x264_param_t *,char const *)"

main.obj : error LNK2019: unresolved external symbol "struct x264_t * __cdecl x264_encoder_open_136(struct x264_param_t *)"

%PROJECT_DIR%: fatal error LNK1120: 3 unresolved externals

Linker scans libx264.lib, but can't find anything inside.

Searching .\lib\libx264.lib:

With dumpbin /HEADERS I can actually find the declaration I need, but linker is unable to do it.

try including using C style bindings.

extern "C" {
#include <x264.h>
}
