Summary0014561: Errors with add_libaray(name INTERFACE) when TARGET_SUPPORTS_SHARED_LIBS is false
Descriptioncmake version 2.8.12.20131111-g13da

When using add_libaray(name INTERFACE) command the following warnings/errors are reported by cmake when TARGET_SUPPORTS_SHARED_LIBS is FALSE. Embedded cross compile targets usually do not support shared libs.

(see also Steps To Preproduce)

> cmake -H. -Bbuild
-- Building for: Visual Studio 11 2012

CMake Warning (dev) at CMakeLists.txt:6 (add_library):
  ADD_LIBRARY called with MODULE option but the target platform does not
  support dynamic linking. Building a STATIC library instead. This may lead
  to problems.
This warning is for project developers. Use -Wno-dev to suppress it.

You have called ADD_LIBRARY for library foo without any source files. This typically indicates a problem with your CMake
Lists.txt file
-- Configuring done
CMake Error: CMake can not determine linker language for target: foo
-- Generating done
-- Build files have been written to: C:/xxx/build

> echo %ErrorLevel%

Steps To ReproduceCreate CMakeLists.txt with following content:


cmake_minimum_required(VERSION 2.8.12.20131009)
set_property(GLOBAL PROPERTY TARGET_SUPPORTS_SHARED_LIBS FALSE)
add_library(foo INTERFACE)

run following command:

cmake -H. -Bbuild
echo %ErrorLevel%
