How to install multiple FILE_SET for a library in a generic way?

Development
21

Thanks, that helps.

Q 1: What COMPONENT names should be typically used for HEADERS and CXX_MODULES?

Q 2: Would it be possible, that instead of sending an error message, CMake install() could install the FILE_SET HEADERS itself to the default DESTINATION?

22

devel or some variant thereof. They’re useful for development packages (sdks) of the project.

I’d rather not continue to encourage projects to dump things directly into $prefix/include rather than claiming a subdirectory.

23

Yes, but if it is used like this:

target_sources(
    ${TARGET_NAME}
    PUBLIC
        FILE_SET public_headers
            TYPE HEADERS
            BASE_DIRS ${PROJECT_SOURCE_DIR}/include
            FILES
                ${PROJECT_SOURCE_DIR}/include/beman/execution/execution.hpp
                ${PROJECT_SOURCE_DIR}/include/beman/execution/functional.hpp
                ${PROJECT_SOURCE_DIR}/include/beman/execution/stop_token.hpp
                ${PROJECT_SOURCE_DIR}/include/beman/execution26/execution.hpp
                ${PROJECT_SOURCE_DIR}/include/beman/execution26/stop_token.hpp
# ...
)

see my PR #215

The issue here is that #include <beman/execution/execution.hpp> works without any -I flags (when installed system-wide in a default location). I’d rather see it installed to /usr/include/beman-executors-1.0/beman/….

OK, then for Boost v1.90.0 I may install i.e.
