Undefined Reference errors when building Tesseract OCR

[Mich Po]

I added these lines to CMakeLists.txt in Tesseract, it builds to 99% then I get a lot of undefined reference errors below.

The leptonica library is built on the same machine using the same arm toolchain. 

set(Leptonica_DIR "C:/opencv/leptonica/build")
set(Leptonica_LIBRARIES} "C:/opencv/leptonica/build/src")
add_library(leptonica STATIC IMPORTED)
set_target_properties(leptonica PROPERTIES
  IMPORTED_LOCATION "C:/opencv/leptonica/build/src/libleptonica.so"
  INTERFACE_INCLUDE_DIRECTORIES "C:/opencv/leptonica/build/src"
)
find_package(Leptonica ${MINIMUM_LEPTONICA_VERSION} REQUIRED CONFIG)

What am I missing here?

Seem like you miss to learn tools you are using ;-) 

Because otherwise you would know that you forget to link your output (tesseract ?) with missing library (leptonica)
