main question: Is there a configuration for cmake, to show or ignore compiler warnings/errors only from a certain directory?
alternative solution: How can I toggle this in QtCreator?
background / motivation: I'm working on a bigger CMake-project and want to focus on warnings and errors only from my subproject. I'm working with QtCreator and it annoys me to look for "my" errors/warnings under a pile of foreign ones.

cmake:48 (include) CMakeLists. txt:208 (find_package) This warning is for project developers. Use -Wno-dev to suppress it. You can disable the warning like this when you are configuring your build.
CMake is a meta build system that uses scripts called CMakeLists to generate build files for a specific environment (for example, makefiles on Unix machines). When you create a new CMake project in CLion, a CMakeLists. txt file is automatically generated under the project root.
CMake can generate a native build environment that will compile source code, create libraries, generate wrappers and build executables in arbitrary combinations. CMake supports in-place and out-of-place builds, and can therefore support multiple builds from a single source tree.
You can set compiler warning options in CMake at least for certain target or certain files.
# For target set_target_properties(your_project_name PROPERTIES COMPILE_FLAGS "...") # For files set_source_files_properties( ${list_of_your_files} PROPERTIES COMPILE_FLAGS "..." ) It is also possible to set the options per-folder basis by separating your project as subproject, add it using add_subdirectory(your_project) and in your project CMakeLists.txt use add_definitions(...).
From CMake documentation:
add_definitions Adds flags to the compiler command line for sources in the current directory and below.
