cmake to make multiple executable files

问题

Currently, I have CMakeLists and hoge.cpp in a directory, and running CMakeLists and make command generates hoge executable file.

Now I added hoge2.cpp and want to be able to generate two different hoge and hoge2 executable files by running CMakeLists and "make hoge" and "make hoge2" commands.

How can I do this?

回答1:

Create two build targets in your CMakeLists.txt file.

add_executable( hoge hoge.cpp )
add_executable( hoge2 hoge2.cpp )

Then you can run (from same directory as your CMakeLists.txt file,

cmake --build . --target hoge

For the other build target use

cmake --build . --target hoge2

You can refer to the CMake documentation or the man pages for more information. Try running CMake with just the --build flag to get help.
