I have been testing the OPTIONAL signature for enable_language using the
following simple CMakeLists.txt file:
*******
cmake_minimum_required(VERSION 2.6.4)
project(test NONE)
enable_language(C OPTIONAL)
message(STATUS "CMAKE_C_COMPILER_WORKS = ${CMAKE_C_COMPILER_WORKS}")
*******
According to the documentation the OPTIONAL signature is to help
CMake-based build systems deal smoothly with bad/broken compilers by
allowing them to take their own actions to deal with the compiler issue
based on the value of CMAKE_<languageName>_COMPILER_WORKS. However, the
OPTIONAL signature does not work and bad/broken compilers error out before
the above message command can be reached. The same issue also occurs for
C++ and Fortran.
Yes, please report this in the bug tracker.
DONE, see http://public.kitware.com/Bug/view.php?id=9220.
