configure: error: C++ compiler cannot create executables

[GoogleCodeExporter]

I've been trying to solve this issue for a couple of days but without success. 
I am building a static library written in C, which uses other static libraries 
(like curl, libevent, defined as ExternalProjects in CMake and compiled from 
sources). The output static library is merged from static dependencies and 
library itself. After upgrading to iOS 7 and OS 10.9 I cannot compile library 
dependencies due to error described below.

What steps will reproduce the problem?

1. cmake  -DCMAKE_TOOLCHAIN_FILE=../iOS/iOS.cmake -DIOS_PLATFORM=OS  -GXcode ..
2. xcodebuild  -configuration Debug

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Latest version of ios-cmake, on OS X Mavericks, trying to cross compile against 
iOS 7.0.

Please provide any additional information below.

I've been successfully using ios-cmake on OS X 10.8 and iOS 6.0. After 
upgrading I cannot get it working.
I managed to get it somehow working using:

1. cmake  -DCMAKE_TOOLCHAIN_FILE=../iOS/iOS.cmake -DIOS_PLATFORM=SIMULATOR  
-GXcode ..

but the output binary is somehow corrupted:

lipo -info build/Debug/library.a  
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/u
sr/bin/lipo: archive member build/Debug/library.a(base64.o) cputype (16777223) 
and cpusubtype (3) does not match previous archive members cputype (7) and 
cpusubtype (3) (all members must match)

I tried reinstalling macports (to have new version of cmake), installed latest 
Xcode (5.0.2), latest command-line-tools and accepted license for 
command-line-tools (which could also generate similar error from clang/gcc).

I don't know if that is a bug ios-cmake, but I would appreciate any help.

Cheers,

Tomasz

This is largely the same problem as issue #11. The iOS-cmake toolchain was 
never written to support compiling executables, only libraries, as the errors 
indicate:

"configure: error: C compiler cannot create executables"

My comments on #11 add some details.
