You can specify linker flags in target link libraries

User · Answer

It depends a bit on what you want    A  If you want to specify which libraries to link to  you can use find library to find libs and then use link directories and target link libraries to    Of course  it is often worth the effort to write a good find package script  which nicely adds  imported  libraries with add library  YourLib IMPORTED   with correct locations  and platform build specific pre- and suffixes  You can then simply refer to  YourLib  and use target link libraries   B  If you wish to specify particular linker-flags  e g   -mthreads  or  -Wl --export-all-symbols  with MinGW-GCC  you can use CMAKE EXE LINKER FLAGS  There are also two similar but undocumented flags for modules  shared or static libraries   CMAKE MODULE LINKER FLAGS CMAKE SHARED LINKER FLAGS CMAKE STATIC LINKER FLAGS

If you want to add a flag to every link  e g  -fsanitize address then I would not recommend using CMAKE   LINKER FLAGS  Even with them all set it still doesn t use the flag when linking a framework on OSX  and maybe in other situations  Instead use link libraries     add compile options  -fsanitize address   link libraries  -fsanitize address     This works for everything
