Commands

IXM's real power lies in the robust set of commands provided to CMake project maintainers. These are a set of functions and macros (in otherwise "commands", as CMake calls them) to allow project maintainers to implement more powerful constructs with less work or "hardening".

This section is specifically for people who might be implementing CMake functions, or find_package modules, rather than editing a CMakeLists.txt file.

For this reason, every command in IXM's API is intended to be called via cmake_language(CALL). This might seem burdensome, however it allows users to write their own wrapper commands if so desired. The overhead of calling cmake_language(CALL) is minimal, and also makes it stand out when someone is calling an IXM based command.
