How can I pass arguments to ranlib using cmake?

Question

How can I pass an argument to ranlib when compiling a static library with CMake?

I tried:

set_target_properties(myLibrary STATIC_LIBRARY_FLAGS "--plugin /usr/lib/gcc/x86_64-linux-gnu/4.9/liblto_plugin.so")

and this worked for ar but not for the subsequent ranlib command.

Answer 1

Have you tried this?

SET(CMAKE_C_ARCHIVE_FINISH   "<CMAKE_RANLIB> -no_warning_for_no_symbols -c <TARGET>")
SET(CMAKE_CXX_ARCHIVE_FINISH "<CMAKE_RANLIB> -no_warning_for_no_symbols -c <TARGET>")

On the Mac, this is how I pass the "-no_warning_for_no_symbols" flag to ranlib.

Note: The SET commands don't modify the ranlib command used as part of an installation by running "make install." CMake's installer code does not generate installation scripts that allow for options to be added to ranlib.

For CMake 3.13+, use STATIC_LIBRARY_OPTIONS:

set_property(
    TARGET myLibrary
    APPEND
    PROPERTY STATIC_LIBRARY_OPTIONS "-no_warning_for_no_symbols"
)

For older versions of CMake, use STATIC_LIBRARY_FLAGS:

set_property(
    TARGET myLibrary
    APPEND
    PROPERTY STATIC_LIBRARY_FLAGS "-no_warning_for_no_symbols"
)

this did not work for me – Undershoot

Since CMake 3.13, there is STATIC_LIBRARY_OPTIONS. I modified my answer to reflect this. – Balkanize
