You need to defer the evaluation of the include directory to generate
time, which will know what exactly build type is needed. This is done
by using `$<CONFIG>` instead of `${CMAKE_BUILD_TYPE`.
Something like the following should work:
set(directory
"${CMAKE_CURRENT_BINARY_DIR}/ComponentsLib_autogen/include_$<CONFIG>")
target_include_directories(ComponentsLib INTERFACE ${directory})
