[CMake] Linked Imported Library in Visual Studio Showing NOTFOUND

[Dustyn Blasig]

Hi All,

I'm trying to debug an issues where an imported shared library is showing
up in the linker command as not found, but within the CMake generation the
target seems to exist.

# CMakeLists.txt ####################

include(bar.cmake)

add_library(foo SHARED)

if(TARGET bar)
  target_link_libraries(foo PUBLIC bar)
endif()

# bar.cmake #######################

add_library(bar SHARED IMPORTED)

...


On Linux, the link command contains the correct *-L<bar path>* and *-lbar*
options. However, on Windows (Visual Studio) the linker command has
"bar-NOTFOUND" instead of bar.lib as it should, even though bar should only
be added as a dependency *if* it exists.

How can I debug why this would happen? Is there a way to have CMake dump
more information about that target?

Thanks!
