Summary0012392: CMakeFindEclipseCDT4.cmake ignores CMAKE_CXX_COMPILER_ARG1 in compiler invocation
DescriptionWhile trying to find system include dirs, in the script CMakeFindEclipseCDT4.cmake the compile is called with:
 ... COMMAND ${_compilerExecutable} -v -E -P -x ${_lang} -dD dummy ...
When using something like ccache or distcc these commands are called directly with the parameter above and complain about unknown options -v.
In the lines:
  SET(_compilerExecutable "${CMAKE_CXX_COMPILER}");
and
  SET(_compilerExecutable "${CMAKE_C_COMPILER}");
the compiler arguments like ${CMAKE_CXX_COMPILER_ARG1}, ${CMAKE_C_COMPILER_ARG1}... are not used.
Steps To Reproducewith:
  CC="ccache gcc" CXX="ccache g++" cmake -G "Eclipse CDT4 - Unix Makefiles" .
the .cproject does not contain system includes.

To view the problem use:
  MESSAGE(STATUS "gccOutput: ${_gccOutput}")
  MESSAGE(STATUS "gccStdout: ${_gccStdout}")
after invocation of
  EXECUTE_PROCESS(COMMAND ${_compilerExecutable}...)
TagsNo tags attached.

 Probably not a good solution (have not written so much cmake code before), but working for the test cases I've here:

Added the if block in the CXX part
    SET(_compilerExecutable "${CMAKE_CXX_COMPILER}")
    IF (NOT ("${CMAKE_CXX_COMPILER_ARG1}" STREQUAL ""))
      STRING(REGEX REPLACE "^ +" "" _compilerArg ${CMAKE_CXX_COMPILER_ARG1})
    ENDIF (NOT ("${CMAKE_CXX_COMPILER_ARG1}" STREQUAL ""))
and in the C part
    SET(_compilerExecutable "${CMAKE_C_COMPILER}")
    IF (NOT ("${CMAKE_CXX_COMPILER_ARG1}" STREQUAL ""))
      STRING(REGEX REPLACE "^ +" "" _compilerArg ${CMAKE_C_COMPILER_ARG1})
    ENDIF (NOT ("${CMAKE_CXX_COMPILER_ARG1}" STREQUAL ""))
and
  EXECUTE_PROCESS(COMMAND ${_compilerExecutable} ${_compilerArg} -v -E -P -x ${_lang} -dD dummy

I'm not sure if there should be quotes like:
  EXECUTE_PROCESS(COMMAND "${_compilerExecutable}" "${_compilerArg}" -v -E -P -x ${_lang} -dD dummy

 In the .cproject file the runAction for the scanner does not get the arguments, either:
 <scannerInfoProvider id="specsFile">
   <runAction arguments="-E -P -v -dD ${plugin_state_location}/${specs_file}" command="/usr/bin/ccache" useDefault="true"/>

I did not find the source, where .cproject is generated, to analyse the problem further.

 The sources are in Sources/cmExtraEclipseCTD4Generator.cxx.

I committed a patch which should make this work for you (at least my tests were successful) to cmake stage (HandleCMAKE_CXX_COMPILER_ARG1InEclipse branch) and merged it into next.

Hopefully it will still make it into 2.8.6.
