Summary0007108: to_native_path/to_cmake_path completely broken on cygwin
DescriptionHello

I am running cmake under cygwin on windows with some Platform files adapted to
be able to use the intel compiler. I am trying to find the include files (and libraries) of Intels mkl libraries with the following
cmake code

 IF(WIN32)
    IF(MSVC OR CMAKE_CXX_COMPILER_ID STREQUAL "Intel" OR CMAKE_COMPILER_IS_MINGW )
      IF(CMAKE_GENERATOR MATCHES "^Unix Makefiles")
        FILE(GLOB MKL_INCLUDE_PATH_LIST_TMP "/cygdrive/c/Program Files/Intel/MKL/*/include")
        FILE(GLOB MKL_LIB_PATH_LIST_TMP "/cygdrive/c/Program Files/Intel/MKL/*/ia32/lib")
      ELSE(CMAKE_GENERATOR MATCHES "^Unix Makefiles")
        FILE(GLOB MKL_INCLUDE_PATH_LIST_TMP "C:/Program Files/Intel/MKL/*/include")
        FILE(GLOB MKL_LIB_PATH_LIST_TMP "C:/Program Files/Intel/MKL/*/ia32/lib")
      ENDIF(CMAKE_GENERATOR MATCHES "^Unix Makefiles")
    ENDIF(MSVC OR CMAKE_CXX_COMPILER_ID STREQUAL "Intel" OR CMAKE_COMPILER_IS_MINGW)
  ELSE(WIN32)
    FILE(GLOB MKL_INCLUDE_PATH_LIST_TMP /opt/intel/mkl/*/include )
    FILE(GLOB MKL_LIB_PATH_LIST_TMP /opt/intel/mkl/*/lib/${MKL_BITDIRSUF_TMP})
  ENDIF(WIN32)
  FIND_PATH(MKL_INCLUDE_PATH_TMP mkl_dfti.h PATHS /usr/include /usr/local/include /u/formes/share/include ${MKL_INCLUDE_PATH_LIST_TMP} )

Now in cmake 2.4.8 this returned

/cygdrive/c/Program Files/Intel/MKL/10.0.1.014/include

while in cmake 2.6.0 it creates

c:\Program Files\Intel\MKL\10.0.1.014\include

a path that it found in the environment variable INCLUDE

I would have expected that in a unix makefile generator the variable should be automatically converted to unix path style.

Then I thought to use the to_cmake_path/to_native_path facilities to convert the path to unix flavor. (BTW I am not quite sure what native means in cygwin compiled cmake on windows).
Neither of these two did anything useful though. Both ended up with something like

"c" "/Program Files/Intel/MKL/10.0.1.014/include"

which after looking in the source code is obviously due to the fact that
the fist thing the TO_*_PATH commands do is

 #if defined(_WIN32) && !defined(__CYGWIN__)
  char pathSep = ';';
#else
  char pathSep = ':';
#endif
  std::vector<cmsys::String> path = cmSystemTools::SplitString(i->c_str(), pathSep);

this means for CYGWIN it will always use ":" as path separator splitting the c from the rest and then converting to unix style path. So in short the path conversion for cygwin is working only in one (completely useless) case:

unix style path -> unix style path
