How to skip some targets using commnd line (CMake)

I'm have dependency on Xerces-c++ and for instal target it always builds example executables and documentation. That consumes ~50% of build time (6 mins on my build VM).

My current build command is cmake --build ${proj}\build_${platform} --config RelWithDebInfo --target install --parallel.

How can I skip non essential targets?

It's third party dependency, so I don't want to modify CMakeLists.txt.

Solution

  • According to the source there is no option to control the build of samples

    add_subdirectory(samples)

    ref: https://github.com/apache/xerces-c/blob/master/CMakeLists.txt#L172

    But you can patch it !

    option(BUILD_SAMPLES "Build samples" ON)
message(STATUS "Build samples: ${BUILD_SAMPLES}")
...
if(BUILD_SAMPLES)
  add_subdirectory(samples)
endif()

    note: you can also enable CMP0077 if you have a super build...
