clang-tidy cmake exclude file from check

If some property - like CXX_CLANG_TIDY - is only available on target level, you have to move the files you want to have different settings for into a separate new target itself.

This can be done by using OBJECT libraries.

In your case something like:

add_library(
    target_no_static_code_analysis
    OBJECT
        path/to/file.cpp
        path/to/file.h
)

# NOTE: Resetting only needed if you have a global CMAKE_CXX_CLANG_TIDY
set_target_properties(
    target_no_static_code_analysis
    PROPERTIES
         CXX_CLANG_TIDY ""
)

...
add_library(target ${other_srcs} $<TARGET_OBJECTS:target_no_static_code_analysis>)
