Compilation failure on Intel Mac of recent builds

[Ivan-Shestakov]

Describe the bug

When trying to compile the game using latest master, I'm getting this error:

src/third-party/imgui/imgui_freetype.cpp:38:10: fatal error: 'ft2build.h' file not found

Here is my compile command

gmake -j 12 RELEASE=1 TILES=1 LOCALIZE=1 SOUND=1 CLANG=1 ASTYLE=0 RUNTESTS=0 LINTJSON=0

System information (from uname -a)
Darwin 23.6.0 Darwin Kernel Version 23.6.0: Wed Jul 31 20:48:44 PDT 2024; root:xnu-10063.141.1.700.5~1/RELEASE_X86_64 x86_64

Since I ain't good in git bisect command, I can't pinpoint which commit has broken this. But going back a few days, allows for successful build.

Looking on recently merged pull requests, I found this one https://github.com/CleverRaven/Cataclysm-DDA/pull/77289/files
When looking at it's affected files, it shows exactly the error I'm having

@katemonster33 - any idea how to fix on Mac?

We are aware of this. If you're using homebrew, try installing freetype with brew install freetype

[Ivan-Shestakov]

Found the reference to freetype in Linux sections in https://github.com/CleverRaven/Cataclysm-DDA/blob/master/doc/COMPILING/COMPILING.md - but having freetype 2.13.3 installed doesn't help.
BTW, I do have ft2build.h in the freetype install location at /usr/local/Cellar/freetype/2.13.3/include/freetype2/ft2build.h

Hello, did #77360 fix this?

[perryprog]

This is still an issue for Apple Silicon as Homebrew on macOS Apple Silicon installs headers to /opt/homebrew/include not /usr/include.
Example patch that would fix it for Apple Silicon (and break it for Intel):

diff --git a/src/third-party/CMakeLists.txt b/src/third-party/CMakeLists.txt

(Though this still leaves a linking error... it seems like the target_link_libraries call isn't finding freetype at /opt/homebrew/lib/libfreetype.dylib for me, though manually specifying that gets it to work for me.)

#77818 fixed CI, #77413 fixed make builds.

Whups, didn't mean to close, cmake is still busted. But cmake is lower tier supported.
