Have you tried add BEFORE in target_include_directories and
include_directories? Like this:

Index: src/CMakeLists.txt
--- src/CMakeLists.txt.orig
+++ src/CMakeLists.txt
@@ -37,8 +37,8 @@ add_library(llama
             unicode.h
             )
 
-target_include_directories(llama PRIVATE .)
-target_include_directories(llama PUBLIC ../include)
+target_include_directories(llama BEFORE PRIVATE .)
+target_include_directories(llama BEFORE PUBLIC ../include)
 target_compile_features   (llama PRIVATE cxx_std_17) # don't bump
 
 target_link_libraries(llama PUBLIC ggml)



maybe it needed to add AFTER for other include dirs as well.
