[CMake] Toolchain.cmake causing find_library problems

[Dixon, Shane]

So "gcc-fm.exe main.c -rdynamic"  fails ?  
Yes, it fails.

Does "gcc-fm.exe main.c -shared"  work ?  
Yes, -shared seems to work.

I'm still having success with FIND_PATH, but FIND_LIBRARY fails:

In toolchain.cmake:
INCLUDE( CMakeForceCompiler )
SET( CMAKE_SYSTEM_NAME Linux )
CMAKE_FORCE_C_COMPILER( gcc-fm GNU )
CMAKE_FORCE_CXX_COMPILER( g++-fm GNU )
SET( CMAKE_FIND_ROOT_PATH 
  "C:/gcc-fm"
  "C:/Program Files/Eracom/ProtectProcessing Orange SDK"
  "C:/Program Files/Eracom/ProtectToolkit C SDK" )
SET( CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER )
SET( CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY )
SET( CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY )

In CMakeLists.txt
FIND_PATH( ERACOM_PPO_INCLUDE_DIR fmerr.h )
FIND_PATH(ERACOM_PTKC_INCLUDE_DIR cryptoki.h )
FIND_LIBRARY( ERACOM_XXX_LIBFMCRT_LIBRARY libfmcrt
		  PATH_SUFFIXES armfm )
FIND_LIBRARY( ERACOM_XXX_CRYPTOKI2_LIBRARY cryptoki2 )

Both the FIND_PATH's pass and both FIND_LIBRARY's fail again.  I thought maybe it's because the paths have a space so I moved them to a folder that has no spaces and still the same issue.

Here are all the paths:
C:\Program Files\Eracom\ProtectToolkit C SDK\include\cryptoki.h
C:\Program Files\Eracom\ProtectProcessing Orange SDK\include\fmerr.h
C:\Program Files\Eracom\ProtectToolkit C SDK\lib\cryptoki2.lib
C:\Program Files\Eracom\ProtectProcessing Orange SDK\lib\armfm\libfmcrt.a

Does "gcc-fm.exe main.c -shared"  work ?

Ok.
SET( CMAKE_FIND_ROOT_PATH 
     "C:/Program Files/Eracom/ProtectProcessing Orange SDK"
      "C:/Program Files/Eracom/ProtectToolkit C SDK")

and then in the CMakeLists.txt:

FIND_LIBRARY( ERACOM_XXX_LIBFMCRT_LIBRARY fmcrt
              PATH_SUFFIXES armfm )

FIND_PATH( ERACOM_PTKC_INCLUDE_DIR cryptoki.h )

should work.
If the library is not found, there is probably still an issue with using the 
correct prefixes/suffixes due to using Windows as a host (I don't think too 
many people have done this yet with cmake).

Just using "fmcrt" in find_library() should be enough, cmake will add the 
necessary prefixes/suffixes itself.
