`MyConsumer/CMakeLists.txt` contains this:
```auto
cmake_minimum_required(VERSION 3.14)
project(MyConsumer
VERSION 1.0.0
LANGUAGES C
)
find_package(MyLib 1.1.0 REQUIRED)
message("MyLib_FOUND ${Siliko_FOUND}")
add_executable(MyConsumer)
target_sources(MyConsumer PUBLIC src/main.c)
target_link_libraries(MyConsumer PRIVATE MyLib::MyLib)
```
I tried building MyConsumer manually and found that the the difference between getting this error and not was whether or not I used `-F ../build-MyLib/install/usr/local`. So, I tried adding this to the generated MyLibConfig.cmake file:
```auto
set_target_properties(MyLib::MyLib PROPERTIES
INTERFACE_COMPILE_OPTIONS "-F${_IMPORT_PREFIX}"
)
```
With this addition, MyConsumer builds, links, and runs without a problem.
Is there some way I can get CMake to generate `MyLibConfig.cmake` with this, or somehow get clang to look for the framework at compile time in the directory where it was found?

I finally figured something out, but it relies the `_IMPORT_PREFIX` variable directly, which isn’t optimal, and I assume subject to change.
if I replace `# FIXME: framework path` with the following, I get what I need:
```auto
set_target_properties(MyLib PROPERTIES
INTERFACE_COMPILE_OPTIONS "$"
)
```
