 ECMEnableSanitizers
 -------------------
 
 Enable compiler sanitizer flags.
 
 The following sanitizers are supported:
 
 - Address Sanitizer
 - Memory Sanitizer
 - Thread Sanitizer
 - Leak Sanitizer
 - Undefined Behaviour Sanitizer
 
 All of them are implemented in Clang, depending on your version, and
 there is an work in progress in GCC, where some of them are currently
 implemented.
 
 This module will check your current compiler version to see if it
 supports the sanitizers that you want to enable
 
 Usage
 =====
 
 Simply add::
 
    include(ECMEnableSanitizers)
 
 to your ``CMakeLists.txt``. Note that this module is included in
 :kde-module:`KDECompilerSettings`, so projects using that module do not need to also
 include this one.
 
 The sanitizers are not enabled by default. Instead, you must set
 ``ECM_ENABLE_SANITIZERS`` (either in your ``CMakeLists.txt`` or on the
 command line) to a semicolon-separated list of sanitizers you wish to enable.
 The options are:
 
 - address
 - memory
 - thread
 - leak
 - undefined
 - fuzzer
 
 The sanitizers "address", "memory" and "thread" are mutually exclusive.  You
 cannot enable two of them in the same build.
 
 "leak" requires the  "address" sanitizer.
 
 .. note::
 
   To reduce the overhead induced by the instrumentation of the sanitizers, it
   is advised to enable compiler optimizations (``-O1`` or higher).
 
 Example
 =======
 
 This is an example of usage::
 
   mkdir build
   cd build
   cmake -DECM_ENABLE_SANITIZERS='address;leak;undefined' ..
 
 .. note::
 
   Most of the sanitizers will require Clang. To enable it, use::
 
     -DCMAKE_CXX_COMPILER=clang++
 
 Since 1.3.0.
