How to change the name of the output binary to not be a.out with CMake?

Question

Where can I go to CMakeLists.txt to change the name of the generated file?

Answer 1

Here is a simple CMakeLists.txt

cmake_minimum_required(VERSION 2.6 FATAL_ERROR) project(demo) add_executable(hello hello.cpp) 

This CMakeLists.txt compiles the hello.cpp file into an executable file called hello. You can name the executable file any, using the add_executable operator.

 add_executable(<executable-name> <source1> <source2> ...) 

Answer 2

For the executable, see the target properties OUTPUT_NAME and SUFFIX . The actual exit name if the combination is OUTPUT_NAME . SUFFIX with

• OUTPUT_NAME by default for the target name
• SUFFIX by default
  • everything defined in CMAKE_EXECUTABLE_SUFFIX for your platform (e.g. .exe on Windows platforms)
  • If the suffix is ​​empty, the compiler can add the extension (see. The default extension of the executable file created by g ++ under Cygwin vs Linux )

Thus, the following example will override both defaults:

 add_executable(a ...) set_target_properties( a PROPERTIES OUTPUT_NAME "myname" SUFFIX ".myext" ) 

Generated myname.myext for target a .
