Dialects

IXM provides a Dialects package that allows users to link against INTERFACEIMPORTED libraries to allow users to turn on or off various C++ language dialect features, such as RTTI, Exceptions, fast math optimizations, or turning off the C++ standard library entirely. Some of these dialects can be combined together. Detailed information for each component can be found on their respective pages.

NOTE

Some C++ programmers might argue that there simply are no dialects in C++. These people are wrong, and should be told they are wrong, as these compiler specific features result in users having to write code in a specific way that changes how they approach C++ as a programming language. To refuse to acknowledge this is foolish.

IMPORTANT

This component currently only works with C++ projects. It does not work with C++-like languages such as:

• CUDA
• ObjC++

Support for these languages may be added in the future. Until then, this package will fail to find any components under the following circumstances:

• CMAKE_CXX_COMPILER_ID is empty.
• CMAKE_CXX_COMPILER_ID is not one of GCC, Clang, or MSVC.

Example Usage

In this example, we are explicitly setting Exceptions to be turned off, and RTTI to be turned on.

find_package(Dialect REQUIRED COMPONENTS Exceptions RTTI)
target_link_libraries(MyTarget
  PRIVATE
    Dialect::Exceptions::Off
    Dialect::RTTI::On)
