Summary0013550: CMAKE_C_COMPILE_OPTIONS_PIE not set for Clang
DescriptionI'm trying to use CMAKE_C_COMPILE_OPTIONS_PIE and CMAKE_CXX_COMPILE_OPTIONS_PIE variables, but they are not set when using Clang.

I found this in /usr/share/cmake/Modules/Compiler/GNU.cmake :

  if(NOT CMAKE_${lang}_COMPILER_VERSION VERSION_LESS 3.4)
    set(CMAKE_${lang}_COMPILE_OPTIONS_PIE "-fPIE")
  endif()

Clang is a GNU-compatible compiler (I have version 3.1), but it doesn't pass the check.

Thanks

Good catch. I factored out Clang compiler info files to have their own code path:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=6e34aea9 [^]

Then I used it to add the PIE setting:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=ada9efd3 [^]

Thanks!
