Bug Report

Describe the bug

Cannot build a program with fluent bit dynamic library.

The error log:

In file included from stdout.c:22:
In file included from ../tmp/usr/local/include/fluent-bit/flb_filter.h:26:
In file included from ../tmp/usr/local/include/fluent-bit/flb_regex.h:27:

#include <mk_core/mk_core_info.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~

To Reproduce

• Steps to reproduce the problem:

Clone and set the working directory to fluent-bit.

1. brew install libyaml openssl bison (cmake is already installed in my env and version is 3.17.3)
2. cmake ..
3. make
4. make DESTDIR=pwd/../tmp install

And try to build any arbitrary filter plugin to a shared object. (I tried this with filter_stdout)

Expected behavior

Compiled successfully.

Additional context

I think configured files/libraries like the following links are not installed.

• fluent-bit/lib/monkey/mk_core/CMakeLists.txt

  Lines 146 to 149 in eb70ee7

  	configure_file(
  	"${CMAKE_CURRENT_SOURCE_DIR}/../include/monkey/mk_core/mk_core_info.h.in"
  	"${PROJECT_BINARY_DIR}/include/monkey/mk_core/mk_core_info.h"

Hi, i've also run into this issue trying to build a custom plugin using only the packages provided via apt.
I have the following installed:
fluent-bit fluent-bit-headers fluent-bit-headers-extra at version 2.1.4

The file mk_core_info.h does not seem to be installed along with the other headers:

fluent-bit/lib/monkey/include/CMakeLists.txt

Lines 1 to 11 in 2060c69

	# MK_CORE
	if(NOT WITHOUT_HEADERS)
	install(FILES "mk_core.h"
	DESTINATION include/
	PERMISSIONS OWNER_READ OWNER_WRITE GROUP_READ WORLD_READ)
	file(GLOB headers "mk_core/*.h")
	install(FILES ${headers}
	DESTINATION include/mk_core
	PERMISSIONS OWNER_READ OWNER_WRITE GROUP_READ WORLD_READ)
	endif()

It would be great if this could be fixed, i'm open to providing a patch if this expedites the release.
