Summary0011731: Issue with CheckTypeSize test
DescriptionHello,

after switching from CMake version 2.8.0 to 2.8.3 I ran into the following issue. I have a script named 'FindComLibs1.0.cmake' which does contain the following statement:

include(CheckTypeSize)
check_type_size("void*" _comlibs1.0_void_ptr_size BUILTIN_TYPES_ONLY)

running a CMake project containing a find_package call to this script does produce the following error:

-- Check size of void*
CMake Error: Unknown extension ".0_void_ptr_size.c" for file "E:/prod_xxx_/Build32/caddy/CMakeFiles/CheckTypeSize/_comlibs1.0_void_ptr_size.c".
TRY_COMPILE only works for enabled languages.
Currently enabled languages are: C CXX RC
See PROJECT command for help enabling other languages.
-- Check size of void* - failed

I think that the determination of the file extension is wrongly implemented.
TagsNo tags attached.

 This issue was introduced by a near-complete rewrite of that module:

 This is actually a bug in try_compile that happened to be exposed by the changes to CheckTypeSize and your project's call to it. Fixed:

While at it I also improved the error messages of try_compile to give context information and have better formatting:
