Hi Eike,
thanks for the pointer. I verified, that it works with the current git
version of cmake.
So the problem will be fixed with the next CMake release.

Hi all,
I hope this question hasn't been asked before, I haven't found
anything useful in the archive.
Assume I have the following small CMakeLists.txt file:
CMAKE_MINIMUM_REQUIRED (VERSION 2.8)
PROJECT(testCMakeDeps)
ADD_LIBRARY(foo SHARED foo.cpp)
ADD_LIBRARY(bar SHARED bar.cpp)
ADD_EXECUTABLE(test test.cpp)
TARGET_LINK_LIBRARIES(test foo bar)
ADD_EXECUTABLE(test2 test2.cpp)
TARGET_LINK_LIBRARIES(test2 foo bar)
This creates two executables, which both depend on the same two shared
libraries. When generating a Makefile for this on Linux,
one can start the compilation process via 'make -j2 test test2', i.e.
name two separate targets on the command line.
However CMake seems to generate a Makefile, which does not work
correctly in this case. The shared libraries are generated twice.
This seems to be a CMake issue, not a Make issue, I can write a
Makefile by hand, which works correctly in this case.
Is there any way around the duplicate generation (which sometimes
fails, because the same libraries may be generated simultaneously)?
Could you please try a CMake version from the next branch, I think that
this has been fixed recently.
Eike
