CMake Imported Library Target giving undefined giving undefined symbols on Windows

I'm trying to import libuv into my CMake project so I can link it. I have libuv 1.12.0 installed from here and I placed it in C:\Program Files\libuv\.

project(tls-server LANGUAGES C)
set(LIBUV_ROOT_DIR "C:\\Program Files\\libuv")
add_library(libuv SHARED IMPORTED)
set_property(TARGET libuv PROPERTY IMPORTED_LOCATION "${LIBUV_ROOT_DIR}\\libuv.dll")
set_property(TARGET libuv PROPERTY IMPORTED_IMPLIB "${LIBUV_ROOT_DIR}\\libuv.lib")
add_executable(tls-server "${CMAKE_SOURCE_DIR}/src/main.c")
target_link_libraries(tls-server libuv)

However, given the above code I am still getting undefined symbol errors in Visual Studio:

Error message

How can I fix this? I believe the paths are all correct. I'm also using Windows 10.

Solution

  • I finally managed to solve the issue.

    Firstly I reinstalled the binaries from the target library (libuv). Then, I made sure that my cmake was generating x64 project files by using cmake -G "Visual Studio 14 2015 Win64". That was sufficient to get rid of the undefined symbols error. Then all I needed to do was copy the libuv.dll file to the same directory as the executable file, and everything ran fine.

    If anyone knows why this error occured, please comment so you can help out other people in the future target the cause of the error better.
