Multiple CMakeLists.txt in a project

Question

I have a project with two CMakeLists.txt files: CMakeLists.txt (default) and CMakeLists.2.txt. So my directory tree looks like project |---- CMakeLists.txt |---- CMakeLists.2.txt |---- main.cpp |---- otherfile.cpp I build like: mkdir build cd build cmake .. make

This uses the default CMakeLists.txt file. How can I specify to build using the CMakeLists.2.txt cmake file?

Answer 1

You cannot change the file name of "CMakeLists.txt".

However, if you need different build configuration for one project, you should use the option in cmake:

option(BUILD_STATIC_LIBS "Build the static library" ON)
option(BUILD_SHARED_LIBS "Build the shared library" ON)
option(BUILD_TESTS "Build test programs" OFF)

And build like this:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=OFF DBUILD_TESTS=ON ..
