Yes, that is the only reason.

Can you try the CMakeFindEclipseCDT4.cmake attached to this bug report? I've
wrapped the call to EXECUTE_PROCESS by saving the LANG environment variable
and then setting it to "C", and restoring it after running gcc.  I'm not
entirely sure if this is the right thing to do as I'm not really experienced
with locales at all.

You can test the script by putting the following in your code:
message("C system include dirs = ${CMAKE_ECLIPSE_C_SYSTEM_INCLUDE_DIRS}")
message("C++ system include dirs =
${CMAKE_ECLIPSE_CXX_SYSTEM_INCLUDE_DIRS}")
