[CMake] target_link_libraries is using relative path of library

[Saad Khattak]

Hello,

This is a very strange behavior I am encountering. I am using CMake 3.7.1
with Visual Studio 2015. I have the following as part of a CMakeLists file:

find_library(glfw_LIB_D  glfw3_d ${glfw_LIBRARIES})
find_library(glfw_LIB    glfw3   ${glfw_LIBRARIES})

When I do "message(STATUS ${glfw_LIB_D})" I get the full absolute path.
However, when I add an executable that depends on the library:

add_executable(vk_test  src/vulkan_test.cpp  )
target_link_libraries(vk_test ${glfw_LIB_D})

CMake puts the relative path when I look at my project's project properties:

..\install\glfw\lib\glfw_d.lib

I also tried the following:

target_link_libraries(vk_test
"${CMAKE_SOURCE_DIR}/install/glfw/lib/glfw_d.lib")

And it's still a relative path. Because of this issue, my project will not
compile as Visual Studio is looking for the library in the incorrect folder.

I even set the following, thinking that somehow relative paths got set:

set(${CMAKE_USE_RELATIVE_PATHS} FALSE FORCE)

I still got the same relative path. What is going on?
