How do I get the output path for a CMake project?

I'd like to specify a post-build action that copies files to the build output directory.

${CMAKE_RUNTIME_OUTPUT_DIRECTORY} appears to be empty.

How can I determine the output path for my generated project in my CMakeLists.txt file?

A project has no "output". A runtime target has a "output". The "output" here should be understood as binary/executable resulting from the compilation.

CMAKE_RUNTIME_OUTPUT_DIRECTORY initializes the RUNTIME_OUTPUT_DIRECTORY property of a runtime target.

In case the CMAKE_RUNTIME_OUTPUT_DIRECTORY is empty, then the target will output it's executable in CMAKE_BINARY_DIR. So you can check if CMAKE_RUNTIME_OUTPUT_DIRECTORY is empty, if it is, use CMAKE_BINARY_DIR.
