Linking from ImGuiBundle - ImFontAtlas Linking Problem

Linking from ImGuiBundle - ImFontAtlas Linking Problem:

Date: 2024-06-25

How can I link to ImFontAtlas::AddFontFromFileTTF?
What ".a" file am I missing?

Description:

I downloaded the ImGuiBundle and created the demo XCode App (worked well).I now want to use the
ImGuiBundle build as a basis for my own build, referencing the bundles resources. I cannot
get past the problem that

ImFontAtlas::AddFontFromFileTTF

is not found. The error is:

Undefined symbols for architecture arm64:
"ImFontAtlas::AddFontFromFileTTF(char const*, float, ImFontConfig const*, unsigned short const*)", referenced from:
Install_ImGuiFonts(std::__1::list<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator>, std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator>>>&) in CustomImGuiTools.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Details:

Code Snippet that calls AddFontFromFileTTF

// install fonts:
// ocornut/imgui#5771
// ImFontAtlas* _cpfont_atlas = io.Fonts;
// declared in imgui_draw.cpp

ImFontConfig cfg;
cfg.SizePixels = 15.0f;
ImFont* _cp_font = io.Fonts->AddFontFromFileTTF(_font_file.c_str(), 14.0f); //, NULL, io.Fonts->GetGlyphRangesDefault());
assert(_cp_font);
FontLibrary[_font_file] = _cp_font;
