Summary0010920: CMake allows name collisions between targets
DescriptionCurrently, cmake does not complain when the same target name is declared using both INCLUDE_EXTERNAL_MSPROJECT and ADD_LIBRARY. The behavior (when both are used with the same name) appears to be unreliable between versions, and to depend on the order in which the two commands appear.

CMake should report an error whenever the same target name is used for different targets. Currently, it does this for LIBRARY and EXECUTABLE target types; but for some UTILITY target types (such as the above mentioned INCLUDE_EXTERNAL_MSPROJECT), it does not report any error or warning.

The following CMakeLists.txt reproduces the problem. (To test it, create empty foo.c and bar.c files). It should generate an error message, because the Foo target name is reused.


 ADD_LIBRARY (Foo STATIC foo.c)
 ADD_EXECUTABLE (Bar bar.c)
 TARGET_LINK_LIBRARIES(Bar Foo)
 INCLUDE_EXTERNAL_MSPROJECT(Foo ${CMAKE_BINARY_DIR}/Foo/Foo.vcproj)
