Scan the well-known system locations looking for a library file.
p = os.findlib("libname" [, additionalpaths])
This function does not work to locate system libraries on macOS 11 or later; it may still be used to locate user libraries. From the release notes:
New in macOS Big Sur 11.0.1, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail.
libname
is name of the library to locate. It may be specified with (libX11.so
) or without (X11
) system-specific decorations.
additionalpaths
is a string or a table of one or more additional search path.
The path containing the library file, if found. Otherwise, nil.
Premake 4.0 or later. Non-macOS host systems only.
