MinGW/CMake Tanımsız Referans ZLib

Question

CMake ile oluşturmak ve MinGW ile derlemek istediğim bir projem var. Proje Zlib kullanıyor. Ben CMake ile inşa zaman hiç hata olsun ama MinGW olun çalıştırdığınızda o zaman şu çıktıyı verir:

Herkes Bunu düzeltmek için ne yapabilirim bir ipucu? Kodun ZLib kitaplığını bulamadığını okudum, nasıl bağlarım?

EDIThere benim CMakeLists.txt'imdir. Bunu Git projesinden aldım.

Hatalarınızı yeniden oluşturmak için küçük bir örnek oluşturmaya çalıştım. Ben

cmake_minimum_required(VERSION 3.4) 
project(zlib_test) 
set(ZLIB_TEST_SOURCES zpipe.c) 
add_executable(${PROJECT_NAME} ${ZLIB_TEST_SOURCES}) 

oldu http://zlib.net/zpipe.c

Benim ilk CMakeLists.txt zlib ana sayfasından benim test dosyasını aldı Ve bu formda

cmake_minimum_required(VERSION 3.4) 
project(zlib_test) 

find_package(ZLIB REQUIRED) 
if (ZLIB_FOUND) 
    include_directories(${ZLIB_INCLUDE_DIRS}) 
endif() 

set(ZLIB_TEST_SOURCES zpipe.c) 

add_executable(${PROJECT_NAME} ${ZLIB_TEST_SOURCES}) 
target_link_libraries(${PROJECT_NAME} ${ZLIB_LIBRARIES}) 

için CMakeLists.txt değiştirdikten sonra aynı hataları

[ 50%] Building C object CMakeFiles/zlib_test.dir/zpipe.c.o

var

Derdim yapabilirim e programı.

Yani sorun şu ki: ZLIB, CMakeLists.txt numaralı telefona nereye eklendi? En azından, find_package(ZLIB REQUIRED) numaralı satıra ihtiyacınız var.
