Fails to find spdlog because wrong link flags are supplied

On FreeBSD 13 it fails to find spdlog:

‌

-- Found SPDLOG: /usr/local/lib/libspdlog.so  
-- Performing Test SPDLOG_COMPILES
-- Performing Test SPDLOG_COMPILES - Failed
-- Adding /usr/local/muq_external/include for an SPDLOG include directory.
[...]
#        SPDLOG ----------------> Met with internal build -- Failed compilation test.

‌

The log in CMakeError.log is:

: && /usr/bin/c++ -O2 -pipe -fno-omit-frame-pointer -fstack-protector-strong -isystem /usr/local/include -fno-strict-aliasing -fno-omit-frame-pointer  -DSPDLOG_FMT_EXTERNAL -isystem /usr/local/include -DH5_USE_110_API -fopenmp -pthread -ldl -O2 -pipe -fno-omit-frame-pointer -fstack-protector-strong -isystem /usr/local/include -fno-strict-aliasing -fno-omit-frame-pointer  -DSPDLOG_FMT_EXTERNAL -isystem /usr/local/include -DH5_USE_110_API -fopenmp -pthread -ldl -fstack-protector-strong CMakeFiles/cmTC_5f25b.dir/src.cxx.o -o cmTC_5f25b  -Wl,-rpath,/usr/local/lib  /usr/local/lib/libspdlog.so && :

‌

The reason is that link flags that pkg-config returns:

‌

$ pkg-config --libs spdlog
-L/usr/local/lib -lspdlog -pthread -lfmt

aren’t supplied. Particularly. -lfmt is missing.
