MesonBuild: How to define dependency to a library that cannot be found by `pkg-config`?
As documented here and here
The main use case for this [
declare_dependency()
] is in subprojects.
and
[
dependency()
] finds an external dependency ... withpkg-config
[or] library-specific fallback detection logic ...
You can, instead, use find_library()
provided by the compiler
object and include_directories()
. find_library()
returns an object just like the one declare_dependency()
returns. include_directories()
returns an opaque object which contains the directories.
Assuming you are using a C compiler and your 3rd party library and its header file are /opt/hello/libhello.so
and /opt/hello/hello.h
, you can do:
project('myproj', 'c')
cc = meson.get_compiler('c')
lib_hello = cc.find_library('hello',
dirs : ['/opt/hello'])
inc_hello = include_directories('/opt/hello')
exec = executable('app',
'main.c',
dependencies : [lib_hello],
include_directories : inc_hello)
