[CMake] Toolchain.cmake causing find_library problems

[Dixon, Shane]

The error message I get if I don't force the compiler is this:

http://pastebin.com/m185e1316


The paths are:
C:\Program Files\Eracom\ProtectProcessing Orange SDK\lib\armfm\libfmcrt.a
C:\Program Files\Eracom\ProtectToolkit C SDK\include\cryptoki.h

Ah, just in pasting that I see part of the problem.  Since I'm cross-compiling, I need to point to libfmcrt.a instead of libfmcrt.lib.

Why do you use cmake_force_c/cxx_compiler() ?
It shouldn't be necessary.
How does compiler detection fail otherwise ?

What are the full paths to libfmcrt.lib and cryptoki.h on your system ?
