Summary0013263: SOURCES target property (get_property()) has very inconsistent result - wildly differing path specifications
DescriptionThe appended sample yields the following output:

[amoh@lxamoh build]$ cmake ..
tgt_sources main.cpp;[TEST_ROOT]/get_property_sources_broken_paths/test.rc;blubb.tas
-- Configuring done
CMake Error at CMakeLists.txt:17 (add_library):
  Cannot find source file:

    blubb.tas

  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
  .hxx .in .txx


-- Build files have been written to: [TEST_ROOT]/get_property_sources_broken_paths/build


Note the very inconsistent items in the tgt_sources line shown above:
For (I assume) all language-related files a project-*relative* path will be preserved, whereas for *existing* foreign-language files the *absolute* path to the project-contained file (due to the result returned by the existence check?) will be delivered, plus for *non-existing* foreign-language files the *relative* path will be returned.

Whoa.

Since AFAIK it is recommended practice to add all files within a project to the target (well, at least *.c* and *.h*, maybe NOT *.rc* and other more foreign files?), this inconsistency is an annoying PROBLEM if detected, and a very annoying BUG if undetected.

Thanks!
Steps To Reproducecmake_minimum_required(VERSION 2.6)

project(get_property_sources_broken_paths)

file(WRITE main.cpp "
int main()
{
  #include \"get_property_sources_broken_paths.h\"

  return 0;
}
")

file(WRITE test.rc "")

#add_executable(get_property_sources_broken_paths main.cpp test.rc blubb.tas)
add_library(get_property_sources_broken_paths SHARED main.cpp test.rc blubb.tas)

get_property(tgt_sources TARGET get_property_sources_broken_paths PROPERTY SOURCES)

 Sending old, never assigned issues to the backlog.

(The age of the bug, plus the fact that it's never been assigned to anyone means that nobody is actively working on it...)

If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it: http://www.cmake.org/mailman/listinfo/cmake [^]

It's easy to re-activate a bug here if you can find a CMake developer who has the bandwidth to take it on, and ferry a fix through to our 'next' branch for dashboard testing.
