miniupnpc libdir not detected properly

Attempting to port the GNTL daemon and wallet to FreeBSD 13.1.

There's one show stopper I haven't been able to solve yet, and would appreciate any ideas people here may have.

First, installed dependencies (adapter for FreeBSD based on GNTLs README.md, the list may grow or change later)

pkg install git autoconf automake boost-all cmake gmake doxygen expat gcc gperf graphviz googletest hidapi miniupnpc ldns libevent lzmalib readline libsodium libtool libgudev unbound libunwind libzmq4 pkgconf libxslt

Then, created a dedicated user (gntld) and (as that user) did the following (based on https://github.com/The-GNTL-Project/gntl/):

Code: 
[gntld@gntl ~]$ git clone --recursive [URL]https://github.com/The-GNTL-Project/gntl[/URL]

[gntld@gntl ~]$ cd gntl && git checkout v1.0.4

[gntld@gntl ~/gntl]$ USE_SINGLE_BUILDDIR=1 gmake release
mkdir -p build/release
cd build/release && cmake -D CMAKE_BUILD_TYPE=Release ../..

gmake: *** [Makefile:85: cmake-release] Error 1

At the end of CMakeError.log is this:
Code: 
Performing C SOURCE FILE Test CMAKE_HAVE_LIBC_PTHREAD failed with the following output:

Source file was:
Code: 
#include <pthread.h>

static void* test_func(void* data)
{
  return data;
}

int main(void)
{
  pthread_t thread;
  pthread_create(&thread, NULL, test_func, NULL);
  pthread_detach(thread);
  pthread_cancel(thread);
  pthread_join(thread, NULL);
  pthread_atfork(NULL, NULL, NULL);
  pthread_exit(NULL);

  return 0;
}

The above may not be the real issue, since "The errors being written to CMakeErrors.log during cmake-time are **also** from the tests being run to determine what works and what doesn't. So there's no harm in there being errors in there" (https://www.mail-archive.com/kde-freebsd@kde.org/msg36289.html)


Returning to the original error message:
Code: 
-- Found miniupnpc
CMake Error at CMakeLists.txt:108 (target_link_libraries):
  Cannot specify link libraries for target "miniupnpc" which is not built by
  this project.
Call Stack (most recent call first):
  external/CMakeLists.txt:48 (link_dep_libs)


Checking ./CMakeLists.txt, I find the following:
Code: 
 99 # Properly links a target to a list of library names by finding the given libraries.  Takes:
100 # - a target
101 # - a linktype (e.g. INTERFACE, PUBLIC, PRIVATE)
102 # - a library search path (or "" for defaults)
103 # - any number of library names
104 function(link_dep_libs target linktype libdirs)
105   foreach(lib ${ARGN})
106     find_library(link_lib-${lib} NAMES ${lib} PATHS ${libdirs})
107     if(link_lib-${lib})
108       target_link_libraries(${target} ${linktype} ${link_lib-${lib}})
109     endif()
110   endforeach()
111 endfunction()


And in external/CMakeLists.txt:
Code: 
 46 if(MINIUPNPC_FOUND)
 47   message(STATUS "Found miniupnpc")
 48   link_dep_libs(miniupnpc INTERFACE "${MINIUPNPC_LIBRARY_DIRS}" ${MINIUPNPC_LIBRARIES})
 49   target_include_directories(miniupnpc INTERFACE ${MINIUPNPC_INCLUDE_DIRS})


Doing a grep:
Code: 
[gntld@gntl ~/gntl]$ grep -Er "MINIUPNPC_LIB|MINIUPNPC_INCLUDE" *

[code]

==> Should MINIUPNPC_LIBDIR and MINIUPNPC_LIBRARY_DIRS be /usr/local/lib (instead of /usr/local) ?
    - Probably, since looking at build/release/CMakeCache.txt I find:

[code]
...
UNBOUND_FOUND:INTERNAL=1
UNBOUND_LDFLAGS:INTERNAL=-L/usr/local/lib;-lunbound
UNBOUND_LIBDIR:INTERNAL=/usr/local/lib
UNBOUND_LIBRARY_DIRS:INTERNAL=/usr/local/lib
...
SODIUM_LDFLAGS:INTERNAL=-L/usr/local/lib;-lsodium
SODIUM_LIBDIR:INTERNAL=/usr/local/lib
SODIUM_LIBRARY_DIRS:INTERNAL=/usr/local/lib
... while for miniupnpc:
Code: 
MINIUPNPC_LDFLAGS:INTERNAL=-L/usr/local/;-lminiupnpc
MINIUPNPC_LIBDIR:INTERNAL=/usr/local/
MINIUPNPC_LIBRARY_DIRS:INTERNAL=/usr/local/

What would be the proper way to fix this?
