Summary0011724: CMAKE_RUNTIME_OUTPUT_DIRECTORY breaks try_compile()'s COPY_FILE directive in 2.8.3
DescriptionI have a CMake project that was working fine with 2.8.1. When I upgraded CMake to 2.8.3, I began to see this error at configuration time:

I am making use of CMAKE_RUNTIME_OUTPUT_DIRECTORY. If I comment out the directive that assigns to it, everything works peachy:

I cannot reproduce this:

  cmake_minimum_required(VERSION 2.8)
  set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${FOO_BINARY_DIR}/bin)
  project(FOO C)

The project configures correctly.

Please post a sample CMakeLists.txt file that reproduces the problem and also specify the CMake command line that you use.

You must be setting CMAKE_RUNTIME_OUTPUT_DIRECTORY in a file referenced by
CMAKE_USER_MAKE_RULES_OVERRIDE as you reported in issue 0011725. I'm closing this one as a duplicate because issue 0011725 is the cause of this.

I'm re-opening this because it is not really a duplicate of 0011725 as I originally thought. Although the cause is the same the solution will be different.

I made try_compile's COPY_FILE feature robust against CMAKE_USER_MAKE_RULES_OVERRIDE files that set CMAKE_RUNTIME_OUTPUT_DIRECTORY:

  http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=5792d3a3 [^]

This should fix your project's build. However, this is also a documentation bug:

  http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=a5300f1d [^]

We've always considered this feature an obscure last resort for setting things like CMAKE_C_FLAGS_INIT. The change made for issue 0010902 was correct under expected use cases. We never expected it to be used for anything else.

Even though this fixes the build with your current code, please also fix your project according to the updated documentation.
