Yes.  The relevant change in CMake is here:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=7195aca5

In response to the first report of trouble with this change we have
since added a note about our policy for external language support:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=854369fd

The fix suggested here:

 https://bugs.kde.org/show_bug.cgi?id=309652#c1
 https://bugzilla.redhat.com/show_bug.cgi?id=872829#c2

is:

>   set (COMPILER_SUPPORT_SUBDIRECTORY "")
> else (${CMAKE_VERSION} VERSION_LESS "2.8.10")
>   set (COMPILER_SUPPORT_SUBDIRECTORY "/${CMAKE_VERSION}")

> configure_file(${script_dir}/CMakeCSharpCompiler.cmake.in
>   ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}${COMPILER_SUPPORT_SUBDIRECTORY}/CMakeCSharpCompiler.cmake IMMEDIATE @ONLY)

but would be better written (also untested):

 if(NOT CMAKE_PLATFORM_INFO_DIR) # pre-2.8.10
   set(CMAKE_PLATFORM_INFO_DIR ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY})
 endif()
 configure_file(${script_dir}/CMakeCSharpCompiler.cmake.in
   ${CMAKE_PLATFORM_INFO_DIR}/CMakeCSharpCompiler.cmake IMMEDIATE @ONLY)
